How Often Should Gas Detectors Be Calibrated and Maintained?
Gas detectors are an important element in industrial sectors where gas leakages and explosions can happen. Such detectors accurately detect harmful gases and help in preventing potential hazards. However, it is important to regularly calibrate these detectors for more accuracy and reliability.
Calibration assures the proper functioning of gas detectors with precise readings and protects your workspace from potential gas-related risks. Go through the blog to learn more about calibration and how often your gas detector should be calibrated.
When does a detector need to be calibrated?
How frequently you organise the calibration of your gas detector solely depends on several factors including the type of gas detector, model, frequency of use, environment or placement and application. Some other factors to be considered are
It’s always recommended to be cautious and conscious in such situations. 12 months is the suggested time for testing most manufacturers, governing bodies and legal regulations. For tankers or vessels with increased levels of stored gas, it is advisable to test it every 6 months, at more regular intervals for precision and accurate functioning.
BUMP TESTING:
Bump testing and full calibration differ, although both aim at the accurate functioning of gas detectors. A bump test, otherwise known as a functional test, verifies the gas detector’s performance by exposing it to a known gas concentration. This test checks if alarms are working correctly and if the detector reacts accurately to the existence of gas. On the other hand, a full calibration sets the device’s sensitivity to ensure its readings align with the known concentration of calibration gas.
The frequency of conducting bump tests depends on the type of sensor in the gas detector. For detectors equipped with electrochemical sensors, performing a bump test every 3months is advisable due to their susceptibility to environmental changes.
FULL CALIBRATION:
For accuracy and efficiency, it is always instructed to Regularly calibrate the gas detectors. It is advised that you must send your gas detectors for calibration services annually. This routine helps in ensuring that your monitored equipment performs at its best, offering accurate and reliable readings.
If a gas detector fails a bump test, it simply means that the device probably is not operating right. Hence, there would be a dire need for calibration to diagnose and rectify the problem. Calibrating a detector after failing a bump test ensures reliability and accuracy and provides optimal safety standards.
HOW IS CALIBRATION PROCESS?
The calibration process at MEBD is a specialised and well-equipped service for bringing reliability and precision to your gas detectors. Our process makes us stand out from other companies in the industry. Here is how our step-by-step calibration procedure works:
1. Pre-test visual inspection: First, we visually inspect our gas detector for any physical wear or tear that may be visible on the detector.
2. Pre-test check: Thereafter, we test this device before testing to check its performance level and look for anything that could be different from standard readings.
3. Bump Test: This is an end for verifying whether the detector responds to the gas or not. This test proves that it will and will not respond to alarm conditions.
4. Calibration Calibration: In case the detector fails the bump test, we calibrate it to match the certified gas mixture and align its sensors with the right industry standards.
5. Post-Calibration Test: After calibration, we conduct another test on the device to guarantee its precision and reliability.
6. Certification and Reporting: We issue you with detailed calibration certificates with performance reports for your reference purposes.
We guarantee the reliability of your safety devices because we are recognized as the best gas detection in Qatar. Additionally, we deliver top-notch solutions to ensure that your gas leak detector in Qatar works without a hitch, we are there at every step for your safety.
Remember, the main purpose for calibrating your gas detector is to give you real gas concentration readings. Only by proper maintenance and high-quality devices can you work without fear in hazard-prone industries. Stay safe and stay assured!
