EcoSensors Calibration Information
EcoSensors devices have a variety of different sensors and calibration options and prodedures. These will vary by product and sensor used in that product. See the list below for your specific sensor and relevant calibration information. First, follow our short list of FAQ's to familirize yourself with general calibration inforamtion.
EcoSensors FAQ and General Information
Will I get a Calibration Certificate?
Yes, all EcoSensors products are shipped with a recent calibration certificate showing NIST traceability
How often should my sensor be calibrated?
Factory calibration should be performmed annually on all EcoSensors products to ensure maximum accuracy and safety.
Can I bump-test my EcoSensors product?
Yes, most EcoSensors products measure ozone. A small ambient air ozone generator can be used to bump test the sensor. These are low cost and readily available.
The C-21, and C-12 are VOC sensors. A simple Sharpie marker near the sensor will be a great bump test. Sufficient VOC gasses are emiited from an uncapped marker to bump-test these sensors.

- OEM-1, OEM-2 OS-1X, OS-3
- EX-1X, A-21ZX, C-30ZX
- C-12, C-21 VOC Sensors
- UV-100 Ozone Analyzer
- OG-3 Ozone Sensor Checker
A-22, OS-6, OS-4, SM-X, SM-4, SM-6 and SM-7
These sensors all use the SM-X ozone sensor chip.
The SM-X is a mass proeduced, yet accurate ozone sensor that is considered disposable. There is no calibration option for this esnsor. The expectation is that this $150 sensor chip is replaced annually with a new sensor chip. The SM-X is only available in one range, 0-20 ppm, each device may use that data and display differently, however we keep it simple and can use the same sensor for each device listed above.
The SM-X carries all calibration data, along with a humidity sensor for humidity compensation that is calibrated to work with the sensor. No calibration alterations are necessary or possible with the SM-X sensor chip.
Each of these sensors calibration can be checked throughout the year, using the OG-3 Calibration Checker. The OG3 will easily and quickly verify that the SM-X incorporated on your device is still accurate and reading ozone correctly.
OEM-1, OEM-2, and OS-3
Note: the OS-3 Ozone Sensors are not currently in production, however we can service these devices as long as they continue to function in your application.
These devices all use the SM Replacement Ozone Sensors.
These sensors are not designed to be calibrated or serviced after getting put in use. Therefore the sensor is simply replaced with new, and the old sensor is disposed of. No return policy is required for the old sensor. The cost of the replacement sensor is only $99. This low cost is lower than any factory calibration offered by any vendor we are aware of!
The spare sensor module is availabe in 3 ranges, 0.1, 1.0, and 10.0 ppm (part numbers, SM-0.1, SM-1.0, and SM-10) The OEM-1 can be used interchangeably with any of these three sensor ranges. However, the OEM-2 and OS-3 are built and calibrated for one sensor range, ensure you purchage the right sensor range for your device.
Each of these sensors calibration can be checked throughout the year, using the OG-3 Calibration Checker. The OG3 will easily and quickly verify that the SEN-1 incorporated on your device is still accurate and reading ozone correctly. While the OEM-1 and OEM-2 do not have displays, there is a method to verify calibration. The OEM-1 offers a 0-1 VDC ouput that is linear with the range of your sensor. The OEM-2 provides a 4-20mA output that is linear with the rage of your sensor. Using a multimeter, or volt meter you are able to verify sensor readings without a display.
EX-1X, A-21ZX, C-30ZX, and OS-1X
Note: the OS-1X Ozone Sensors are not currently in production, however we can service these devices as long as they continue to function in your application.
These devices all use an integrated sensor. The best option for calibration is to ship the sensor back to Gas Sensing, or EcoSensors to have a factory calibration performed. Most often, after 1-year of use the sensor needs to be replaced. The sensor in these deivces is soldered onto the board and not replaced without some labor. Follow this link, for detailed instructions on sensor replacement.
If you do choose to purcahse and install your own replacement sensor, they are available for a price of $75 each. It is the same sensor for each device listed here.
Contact us for information in shipping your sensor to us for factory calibration. Calibration cost is $225. This includes the price for a replacement sensor.
Each of these sensors calibration can be checked throughout the year, using the OG-3 Calibration Checker. The OG3 will easily and quickly verify that the sensor incorporated on your device is still accurate and reading ozone correctly.
The C-21 is a great VOC sensor that can be calibrated and adjusted to respond to many VOC gasses quite accurately. Eco-Sensors calibrates each C-21 to generic VOC gasses from the factory.
Bump testing of your VOC sensor can also be performed. We suggestion using something simliar to a common Sharpie marker. These are common, and off-gas a great deal of VOC gasses. Placing this near your C-21 will ensure the sensor is still responsive to some VOC gasses.
The C-21 VOC Sensor can be calibrated to your specifications using detailed instructions provided at the link below:
Replacement sensors for the C-21 are available from Gas Sensing for $50. Please contact us for ordering information.
Contact us for information in shipping your sensor to us for factory calibration. Calibration cost is $125. This includes the price for a replacement sensor.
The UV-100 Ozone Analyzer is a UV based instrucment that is extremely accurate, and extremely sensitive. Great care should be taken with any calibration or lamp replacment.
Calibration of the UV-100 can be peformed by obtaining an ozone reference standard and entering the admin menu of the UV-100. The Zero, and Span settings of the UV-100 can be altered in that menu.
The UV-100 UV bulb can be field replaced using the following instructions:
After the UV lamp has been replaced calibration is required. This can be performed by using a reference standard to perform calibration.
Replacement UV-Lamp = $200
Factory Calibration of the UV-100 = $325
Contact us for information in shipping your device to us for factory calibration.
The OG-3 is a calibration checker designed and built by EcoSensors specifically for EcoSensors products. The OG-3 is a great low cost reference standard for EcoSensors products. A UV-lamp is used to produce a known amount of ozone from the OG-3. It is usually calibrated to 0.1, 1.0 or 10.0 ppm.
The OG-3 ozone output should be checked and adjusted periodically (depending upon use) to kep it accurate. We provide calibration service and repair for the OG-3.
OG-3 Calibration = $150
OG-3 lamp replacement (includes calibration) = $325
Replacement OG-3 Lamp = $175
Contact us for information in shipping your sensor to us for factory calibration.
Using the UV-100 Ozone Analyzer the OG-3 ozone output can be verified and adjusted as needed. See details on this process at the link below:
The UV lamp used inside the OG-3 will get weak and require replaceemnt after some time. If you find your OG-3 lamp is in need of replacement we can provide service to replace this lamp, or you can purchase a lamp from us, install, and calibrate your OG-3 with a UV-100 Ozone Analzyer.
