GAS DETECTOR

Calibration is the process of configuring an instrument to provide the needed result within an acceptable range. It’s the process of ensuring that the instrument is working properly and avoids inaccurate readings. Gas Monitors are life saving instruments that must be calibrated regularly in order to function.

ANNUAL SERVICE

Manufacturers often offer annual inspection. If they don’t, it is highly suggested to get an authorized company to do a full recalibration and (if necessary) repair at least once a year. Even if this is done, gas monitors require regular bump tests and self calibrations to be done onsite by users.

BUMP TEST

This is when you hold the gas detector to a certain level of the gas hazard it is intended for long enough to cause an alarm. It checks that the gas detector is working at all. This should happen BEFORE EVERY USE. If it fails, it needs to be recalibrated.

SELF CALIBRATION

This is done using an internal menu within the gas detector. It requires exposure to the gas blend it was designed for in order to re-establish the accuracy of the sensors. It is IMPERATIVE to use the exact gas concentration and blend for the brand of monitor and to check the expiration dates. If it fails, it must be repaired. Frequency of calibration varies. Always follow manufacturer instructions.
