Calibrating a Gas Detector

A gas leak detection device or gas detector alarm only benefits an individual when it works properly. The device functions to minimize injuries and illnesses because many hazardous conditions cannot be detected with the human senses. Workers need equipment to know when they are approaching or entering a dangerous area, so they can act accordingly. If the device malfunctions, these individuals become at risk of being harmed. However, knowing how to use the equipment serves as only part of the equation when it comes to keeping workers safe.



A gas detector must be calibrated regularly to ensure it works as intended. Calibration remains a key part of equipment checks to prevent harm to workers. How should a device of this type be calibrated? What steps does the worker need to carry out to ensure it is and that the device is providing accurate readings?

What is Calibration Drift?

Calibration drift occurs when a device suffers chemical degradation of the sensors. In addition, it may happen as a result of time. The environmental conditions the detectors are exposed to can negatively impact their performance, and workers may accidentally drop or bump the device or use it in a manner that degrades the electronic components. Calibrating the device helps to restore it to normal functioning.

Workers need to follow the directions provided by the manufacturer to calibrate the device. Many factors play a role in how this task should be carried out and the worker must make certain they are using the proper vna calibration kits or other materials. When using these calibration kits, workers must carry out a bump test and full calibration. What are the differences between the two types of testing?

Bump Testing

Bump testing involves nothing more than exposing the device to a target gas to ensure the alarm triggers properly. Before bump testing, the worker must set the instrument to zero to ensure accurate results. This needs to be done within a controlled environment, so the worker knows what reading they should get during the testing process. If the device does not provide the anticipated reading, the device requires full calibration.

Full Calibration

During a full calibration, the gas monitor reading is adjusted so that it will respond to a concentration of test gas that is known. This process should be carried out after failed bump testing or when the device has sustained damage and the worker doesn't know the extent of this damage. In addition, it needs to be carried out after the device has been serviced.

Every worker must feel confident their gas detector works as intended. In addition, businesses need to know the equipment is working properly for legal purposes. Calibrating the device is essential to ensure this is the case. Calibrate your devices today for peace of mind, knowing you have done everything possible to keep workers safe.
