Our automated notification system will ensure that your calibrated instruments are always up to date.

Our specialized calibration team have years of experience in qualified calibration management of various measuring instruments which can help you to ensure that your equipment is working consistently and accurately.

GAS TESTER CALIBRATION

Multi-gas detectors and other detection technologies are crucial to minimizing injury and illness in the workplace. A lot of hazardous atmospheric conditions can’t be detected through human senses alone, and equipment that can test the air in a confined space can mean the difference between life and death. However, equipment alone can’t protect lives unless workers are properly trained in using and calibrating it. Calibration of gas detectors is just another part of regular equipment checks, and is integral to creating a safe workplace. The experts at have information and advice on proper detector calibration procedures to make sure your gas readings are as accurate as possible.

How to Calibrate

Keeping instrument reference points consistent is important for worker safety. Calibration drift can happen over time because of chemical degradation of sensors and the natural drift in electronic components. Multi-gas detectors are exposed to extreme environmental conditions that can affect their performances, such as temperature, humidity, airborne particles and vapors, sensor poisons and inhibitors, and high concentrations of target gases. Add in that they might get dropped on hard surfaces or in water or handled often enough for the vibrations to affect electronic components, and your devices will need calibration to keep working effectively.

Bump Testing

A bump test before you use a gas monitor is highly recommended and easy to perform. Bump tests expose the gas monitor’s sensors to a target gas to test whether the alarm triggers, before you take the monitor into the field. Instruments must be zeroed before you test them, to provide more accurate results. Your monitor comes with a clip and a hose to secure over the sensor plate; attach the other end of the hose to the calibration gas and regulator, turn on the monitor and let it boot up, and open the regulator to let enough gas to trigger an alarm flow into the monitor. This should take about 10 seconds yet no more than 20 for the monitor to go into alarm. Comparing the reading on the monitor to the quantity of gas present is how you determine if the monitor is properly calibrated. If the response is within an acceptable tolerance range (the detection equipment manufacturer will provide acceptable tolerance ranges), then the calibration is verified; if not, proceed to a full calibration.

 

Full Calibration

If the bump-test results aren’t acceptable, or either after the detector has been serviced or potentially severely damaged, the multi-gas detector needs to be completely calibrated. A full calibration adjusts the gas monitor’s reading so it responds to a known concentration of test gas. Some disposable monitors come with instructions stating that no calibration is required for the life of the instrument, but for safety’s sake, regular bump testing is important to make sure the device responds. The sensors in disposable monitors are the same ones used in unlimited life monitors, are just as sensitive, and are subject to the same kinds of conditions.

Making sure your data is accurate is important for legal protection as well. Multi-gas monitor readings only hold up in court as incontrovertible if the gas detector is properly calibrated before and immediately after each use to ensure it’s functioning properly. Keep a written record of calibrations for the life of each instrument so workers can identify the ones that needed excessive maintenance or are prone to inconsistent readings.
