Gas detectors use sensors to measure target gas levels. Why Calibrate New Sensors? Sensor performance is prone to drift over time and exposure to gaseous environments. That's why you need to calibrate them regularly - to make sure the sensor is working properly.
What does the calibration process involve? Calibration involves testing the sensor against known calibration standards and making adjustments to correct any inaccuracies. "Known Calibration Standard" is the content of the calibration cylinder.
Why do I need to calibrate my gas detector even though it is fairly new? And once it's in service and exposed to gas, the sensor starts to work. Once they start working, they become prone to "drift". Other gases can actually poison some sensors, making them impossible to calibrate.
For example, LEL sensors can be severely affected by exposure to silicon-based products.
Many gas detectors are equipped with a docking station that can be bump tested and fully calibrated on your own premises. If not, the gas detector manufacturer can assist you in performing the calibration.
