Some toxic and harmful gas detectors may experience sensor readings that drift over time or degrade in accuracy. This means their ability to display accurate results diminishes, rather than the machine being damaged or malfunctioning.
There's a straightforward solution: regularly calibrate and verify your instruments. This process will restore the equipment to normal functionality, ensuring they operate at 100% efficiency. However, as each gas detector operates using unique technology, different procedures are required for various types of gas detectors. You must choose the correct method to complete the task.
If your device detects only one gas, it can be manually calibrated or adjusted with certain tools.
Calibrating Gas Detectors Method
Manual Calibration
Portable gas detectors are commonly equipped for manual calibration. Manually calibrating CO2, NH3, or H2S detectors usually involves checking their response to test gases of known concentrations. Continue adjusting the device until its readings match the parameters of the test gas. Just ensure the substance is not expired to confirm the validity of the comparison.
Why Calibration Matters?
Individual gas detectors are crucial in laboratories, manufacturing plants, and other industrial facilities. These locations can produce toxic and flammable fumes, making it essential to monitor the concentration of air around for maintaining a safe and healthy working environment.
Therefore, like any other measuring instrument, gas detectors need to be recalibrated and adjusted periodically to ensure that all sensors and components display accurate readings. This way, your safety officers can respond swiftly to leaks and similar issues.
Utilize a dock extension
If you have dozens of individual gas detectors in your facility, checking each device one by one will be a lengthy and tedious process. Large teams and companies are switching to docking stations.
The docking station is a convenient device that allows for charging and calibration of the gas sensor monitor when not in use. Simply place the detector in the station, and it will automatically adjust its settings overnight. This way, you can head to the factory or lab the next day without worrying about a dead battery or the need for collision testing.
Special Kits and Accessories
Although using extension cables is a convenient method to recalibrate individual gas detectors, they are not inexpensive. Fortunately, obtaining special test kits and accessories is another option. They can save you time, while being affordable and easily accessible.
These kits include everything needed to inspect the equipment and adjust its settings. Some test kits even allow managers to monitor sensor devices from a remote location. Consult with your gas detection system supplier for information on these products.
If you need to adjust other gas detectors, you can refer to the previously calibrated gas detectors. The processing time for each sensor device will not exceed 5 minutes, making it an ideal choice if you use multiple devices at once. The U.S. Occupational Safety and Health Administration (OSHA) recommends performing this check every 6 months, while Chinese law generally requires calibration once a year. Combustible gas detectors listed in mandatory inspection projects must undergo annual verification and calibration.
