Aeroqual R42 Calibration Kit
$150.00

The Aeroqual R42 calibration kit is designed to assist with consistent calibration of Aeroqual sensor heads.


Using either the Series-300, or Series-500 Handheld monitor the Zero and Span settings of the sensor head can be calibrated to your span gas. 

Description

Details

The Aeroqual R42 calibration kit is designed to assist with consistent calibration of Aeroqual sensor heads.

The Calibration Accessory is a simple and effective tool for calibrating sensor heads for handheld and fixed monitors. By delivering a consistent flow of calibration gas to the sensor head, without forcing air at the sensor, it ensures the most accurate calibration possible. It can also be used to humidify the gas which is important for best results with GSS sensors.

Either a Series-300, or Series-500 Handheld monitor is required to make necessary span calibration adjustments.

 

 What do I calibrate - the monitor or the sensor head?

Aeroqual’s unique system of interchangeable sensor heads means they can be calibrated independently of the monitor. If you are sending a sensor head to us for factory calibration, then you do not need to send the monitor back. The monitor base does not need to be calibrated. Note: the Series 300 and 500 monitor bases can be used to calibrate the zero and span of any sensor head (including those from one of our fixed monitors); the Series 200 base can only be used for a zero calibration.

 How do I know my sensor head is reading accurately?

All our sensor heads come with a factory calibration certificate. Over time the sensor head will need to be re-calibrated to ensure it is reading accurately. See below for a full discussion of how and when to re-calibrate. In between calibrations, particularly when the monitor is being used for health and safety purposes, a bump test is used to check the sensor is responding.

 How do I do a bump test?

A bump test typically involves brief exposure of the sensor to a known quantity of gas and making sure the monitor reading corresponds with that concentration. Unlike calibration there is no adjustment of the monitor in response to the level of gas detected. For instructions on how to bump test your handheld monitor, please consult the User Guide.

 What is the difference between a zero and span calibration?

A bump test typically involves brief exposure of the sensor to a known quantity of gas and making sure the monitor reading corresponds with that concentration. Unlike calibration there is no adjustment of the monitor in response to the level of gas detected. For instructions on how to bump test your handheld monitor, please consult the User Guide.

 What is the difference between field and factory calibration?

As the name suggests factory calibration means calibration by the manufacturer or suitably qualified laboratory. Field calibration involves calibration of the sensor head by the end user.

 How do I calibrate my ozone sensor head in the field?

There is an important difference between ozone and other types of gases. Ozone cannot be stored in bottles. Instead ozone must be generated at source using an ozone generator. A zero calibration can be done using a zero air bottle, but for a span calibration you must be able to generate ozone. If you have an ozone generator/calibrator then instructions on field calibration can be found in the User Guide. If you do not have an ozone generator/calibrator then we recommend sending the ozone sensors for factory calibration (see below). Note: this applies for our Perc sensor heads too, because Perc is only available as a solvent.

 How do I calibrate my non ozone sensor head in the field?

For non-ozone sensors, instructions on field calibration using calibration gas can be found in the User Guide.You can watch a video demonstration of a single sensor head calibration here:

 How often do I need to field calibrate my sensor head?

This depends on the level of rigour required in your measurement application. Researchers may calibrate before every measurement they take. But for most people regular calibration is enough to ensure good results. By regular we mean once or twice per year. For the reasons of cost and complexity outlined above, customers tend to calibrate ozone sensor heads less often and instead send them to the manufacturer or laboratory once every year or so.

 How do I factory calibrate my sensor head?

Simply send the sensor head to us or a suitably qualified laboratory. Our charges for factory calibration are quite reasonable. Please contact us for a quotation.

 How often do I need to factory calibrate my sensor head?

If you’re able to field calibrate your sensor head you may never need to send it to us for calibration. However if you want to be 100% sure of the calibration, an annual factory calibration complete with certificate provides ultimate peace of mind. Ozone sensors are hard to calibrate in the field so we recommend sending for factory calibration once every year.
