There are many types of dangerous gases in the atmosphere. While some are detectable, others are not. Toxic gases leaking around environments can be life-threatening, especially if they exist at a high concentration level. This is when life-saving equipment like a personal gas monitor or infrared gas detectors come into play.

These gas monitors help check indoor air quality by detecting gases and alerting individuals when the gas levels become lethal. However, gas detectors should be maintained well to show an accurate reading and avoid unnecessary shutdowns. If these systems show inaccurate readings and alarms don’t work, there’s no use. That’s why manufacturers recommend calibrating the gas sensors.

What Is Gas Monitor Calibration?

Gas monitors that measure the value of a variable require regular calibration gas. During the calibration process, sensors are exposed to gas and tested to see if they provide accurate readings or not. If gas detectors show inaccurate readings, the calibration gas procedures automatically adjust the sensors to show accurate readings. Thus, it helps to ensure the alignment ...
... between the measuring unit and instrument. Following a proper calibration maintenance schedule ensures the gas detectors or monitors read the gas concentration levels in the atmosphere correctly and send alarms to evacuate and save lives.

Why Is It Important to Maintain the Gas Detectors and Calibrate Them Frequently?

It’s of utmost importance to understand that a gas monitor or detector is a safety device that requires regular maintenance to ensure optimal performance. A well-maintained and properly functioning gas monitor could make the difference between life and death. The function of a gas detector is to monitor, measure, and send alarms when the gas concentration levels are high and become lethal in the atmosphere. However, if the equipment isn’t functioning correctly, there’s no use in this life-saving device. So, it makes sense to maintain them regularly.

Schedule Monthly Maintenance

Monthly maintenance of gas monitors is crucial. Ensure to schedule maintenance every month to perform at its optimal level. It’s important to inspect each device in your facility, conduct bump tests on all the devices, do a calibration test, and record the results. This will help track the performance of each gas detector or monitor in the facility and replace them before they give up on you.

However, the calibration frequency depends on the type of gas monitor and the type of usage. Therefore, it’s important for the users to develop a calibration schedule customised to their usage and requirements.
