  • Particulate Matter (PM) sensor

    A new PM (Particulate Matter) sensor will be released in September and is designed to simultaneously measure PM2.5 and PM10 for indoor and outdoor use. This portable particulate monitor will display real-time measurements of particulate matter. (See picture of the display below)

    Particulate Meter readout

    The PM sensor will need to be used with the portable base Series 200, Series 300, or Series 500 that gives the digital readout of the current particulate matter measurement.  Like the other Aeroqual sensors, the PM sensor head can be swapped around and the same base can be used with up to 30 different gas sensors.

    Particulate Matter Sensor

    From the manufacturer Aeroqual: "Field tests have shown the portable particulate monitor provides useful data when compared to traditional ‘reference’ methods. This data will be made available on commercial release of the product."

    GasSensing is excited to offer this new PM sensor in September as we feel it will be a great addition to the Aeroqual sensor line.  In addition to being able to purchase this sensor from GasSensing, we will be offering the PM10/PM2.5 as a rental sensor with the Series 500.

    Feel free to contact us with questions or register your interest in the PM10/PM2.5 Sensor.

  • Wireless Gas Monitoring

    Wireless gas monitoring

    Recently Gas-Sensing introduced a new accessory making it possible to connect gas monitors to the internet. We call this accessory the Wireless Monitoring and Data Logging Kit. This has sparked a lot of interest and we have had excellent feedback from our customers who have purchased and are using this kit.

    How it works

    The Wireless Monitoring and Data Logging Kit works by wiring a current or voltage sensor to the analog outputs, which correspond with the gas concentration on a fixed gas monitor. The current or voltage sensor communicates with a gateway which is connected to the internet, and finally to view and collect the data in real time, you simply open up the online portal with the credentials we provide you.

    Wireless gas monitoring How the wireless monitoring and data logging kit works

    Wireless Sensor                             Wireless Gateway                              Online Portal

    This essentially makes any fixed mount gas monitor we offer wireless and IoT enabled (Internet of Things).

    Advantages to connecting a gas monitor to the internet:

    • Knowledge of gas concentrations anytime, from anywhere by simply opening our app on a smartphone.
    • Free email and SMS text message alerts for alarming situations.
    • 24/7 data logging to view trends over a given amount of time.
    • No monthly fees.

    This accessory will be wired and mounted on your gas monitor before shipment, making this as user friendly as possible.

    Here is one of the success stories we have had since launching the Wireless Monitoring and Data Logging Kit.

    Brandon works for a University and sterilizes laboratories with high concentrations of Hydrogen Peroxide. He would typically treat 3 rooms simultaneously, and all three rooms were connected to a hallway.

    Before contacting Gas Sensing he was unsure of the Hydrogen Peroxide levels achieved  during a treatment inside of the rooms. He also had to sit in the hallway with a handheld monitor during the entire treatment  (4-5 Hours).

    So we provided a simple solution.

    Wireless gas monitoring Wireless monitoring and data logging kit for Hydrogen Peroxide

    We provided him with 3) 0-1000 PPM Hydrogen Peroxide sensors for the rooms being treated, and 1) 0-10 PPM Hydrogen Peroxide Sensor for the hallway to detect any possible leaks.

    This was using the B12 2 Wire Transmitter from ATI, with the remote monitoring and data logging accessory attached.

    This way Brandon could open up the online portal to see his hydrogen peroxide concentrations in real time, and set notifications when specific conditions are met.

    online portal Online portal to view gas concentrations remotely

    This is what Brandon had to say after using these products:

    “ This is the perfect set-up for any facility or company that has to do large scale decontamination projects. It eliminates having to run cables under doors then going back and trying to keep the VHP from leaking out. I’m really impressed because it made my life and job 100x easier. Now I don’t have to sit in the hallway for hours, I can just set the monitor outside and have it send me a notification if it senses anything above 1 PPM! “

  • A21 Gas Sampler

    The ATI A21 Gas Sampler is a now up on GasSensings website and available for purchase.

    A21 Gas Sampler A21 Gas Sampler

    The A21 Gas Sampler is designed to draw a gas sample from a duct, vent stack, enclosed space or hard to reach location and deliver a gas sample to your monitor that can then be located in a more convenient spot.  The sensor can then be located more remotely as the pump that is built into the A21 pulls the gas back to the main monitoring device and will ensure reliable gas sample measurement. It also comes with mechanisms that help to ensure reliable sample measurement. There is a flowmeter on the front panel that allows you to adjust the sample flowrate (typically around 500 cc/min).  Another important part of this device is a loss of flow detector that alerts when the system notes loss of flow or low flow that could lead to inaccuracies in the sample measurement.

    The A21 was designed to be used with the D12 Toxic Gas Transmitter or the B12 Gas Transmitter but can be used with a variety of monitors where you need to pull a sample from a place that is difficult to access.  It can be fabricated to be powered by either 120 VAC or 12 VDC.

    If you aren't sure if this device will work with your current set up, contact us and we'd be happy to figure out a detection system that would be best for you!

  • Peracetic acid (PAA) Health Risks & Guidlines

    Peracetic Acid is used as a cleaner and can be found in many food establishments, medical facilities, agricultural applications, on food processing equipment,  and in pasteurizers in wineries, breweries and beverages facilities. As with all gases, proper application guidelines should be followed and gas levels should be monitored to avoid human safety issues.

    You can find all of the equipment that we offer for measuring and detecting PAA on our website.

    The article below is posted with permission by: http://www.chemdaq.com/blog/

    Peracetic Acid Uses, Health Risks & Workplace Guidelines

    Peracetic or peroxyacetic acid (PAA) is a strong oxidizing agent used for high level disinfection and sterilization at low temperatures. It is water soluble, and leaves no solid residue after rinsing and the end products are only water, oxygen and acetic acid (vinegar), making PAA a very environmentally friendly compound.

    In healthcare, the demand for faster turnaround time of heat sensitive reprocessed multiple-use medical devices led to the development of PAA liquid sterilization, given ethylene oxide’s longer required aeration time at the end of the sterilization cycle to vent the gas. In addition, the food packaging and waste water treatment industries have adopted PAA as a preferred disinfectant and sterilant wash because of its environmental properties.

    Health Risks of PAA Exposure

    As an antimicrobial agent, PAA is broadly effective against a wide range of microorganisms; it disrupts bonds in proteins and enzymes and interferes with cell membrane transportation through the rupture of cell walls, oxidizing essential enzymes and impairing vital biochemical pathways.

    The properties of PAA that make it an efficient sterilant and environmentally friendly make it potentially dangerous to any employees exposed to it in the workplace. Unfortunately the health risks to workers from PAA exposure are not known by many employers. Hospitals, food handling and processing industries commonly use PAA, in concentrations that can be harmful to workers if they are exposed.

    Specifically, the National Institute for Occupational Safety and Health (NIOSH) Registry of Toxic Effects of Chemical Substances identifies PAA as a primary irritant, known tumorigen and mutagen.

    The New Jersey Department of Health and Senior Services Occupational Health Service released a study on the the health effects of PAA exposure. The study also found that PAA is very irritating to the skin, eyes, nose, throat, and lungs, with the potential for causing permanent scarring of the skin, cornea, and throat. Higher exposures in the short term can also cause pulmonary edema as well as liver and kidney effects.
    PAA Workplace Guidelines

    While there are no Occupational Saftey and Health Administration (OSHA )regulations specifically for PAA - most OSHA PELS have not been updated since their initial adoption in 1972 - the Environmental Protection Agency (EPA) has issued Acute Exposure Guideline Levels (AEGLs) for PAA, specifically:

    AEGL-3 (death/permanent incapacity) 1.3 ppm: the threshold above which mortality and/or irreversible effects could be observed for an exposure of up to 60 minutes. AEGL-3 is analogous to the NIOSH Immediately Dangerous to Life or Health (IDLH) chemical listing concentrations and documentation values, which are 75 ppm for hydrogen peroxide and 800 ppm for ethylene oxide.
    AEGL-2 (disability) 0.51 ppm: the threshold level above which intense lacrimation, extreme nose discomfort and transient incapacitation (inability of self protection but without residual consequences) could be observed for an exposure of up to 60 minutes.

    AEGL-1 (discomfort) 0.17 ppm: the level above which discomfort could be observed for an exposure of up to 8 hours per day. AEGL is analogous to the OSHA PEL (1 ppm for both hydrogen and ethylene oxide, calculated as an 8 hour time weighted average. See OSHA Standard 1910.1000, Table Z1 Limits for Hydrogen Air Contaminants and OSHA Standard 1910.1047 for Ethylene Air Contaminants.

  • Calibration Services

    Sensor Calibration

    Why must you calibrate gas sensors?  Calibration is recommended to ensure maximum accuracy and safety.  It verifies the sensor is accurate and providing correct measurement of the gas you are detecting.

    How often should I calibrate my sensor? Factory calibration should be done annually. But we also recommend field check or bump test every 6 months.  Different gasses and sensor manufacturers have different requirements.  You can view their specific requirements using the links below:

    ATI Sensor Calibration Information - http://www.gas-sensing.com/ati-calibration

    Aeroqual Sensor Head Calibration Information - http://www.gas-sensing.com/aeroqual-calibration

    EcoSensors Calibration Information - http://www.gas-sensing.com/ecosensors-calibration

    Factory Calibration

    Your sensor can be sent back to us for calibration.  We will evaluate, calibrate, and return it with a Calibration Certificate providing performance during calibration, date it was calibrated, and date that calibration should be done next.

    How do I return my sensor to be calibrated?

    Your sensor can be sent back to us at:
    Gas-Sensing
    Attn: Calibration
    1322 1st Street
    Hull, IA 51239

    We require that an RMA form be filled out and sent back with your sensor. Contact us to receive this form.

    Calibration Gasses

    Another option is to get gas cylinders of known quantities of gas.  This can be mixed with air to provide span calibration.  This needs to be done according the manufacturers specifications to perform a span gas calibration.   NOTE: This is not an option for all gases as some have a short half-life and cannot be bottled.

    Some gases can be calibrated on site using a calibration kit. For example: the A23-14 provides a consistent flow of calibrated ozone gas for calibration purpose, in a handy portable carry case.

    Gas Calibration Kits can be found on our website.

    Field Calibration

    Field calibration can be performed on-site and is convenient when sending your sensor in to be calibrated is challenging.  In order to perform field calibration you must have calibration gasses or a unit designed to produce a consistent amount of gas, that way you can ensure the sensor is reacting properly.

    Gas Sensing is will to come to your facility and perform Field Calibration.

    Bump Testing

    Bump testing allow you to check and make sure that your sensor is responding to the gas that you are trying to detect.  It is not a precise measurement, but rather, just a check to ensure your monitor is reacting and will respond when gas levels reach a dangerous level. This is not a replacement for calibration.
