1. Ensure accuracy:

The sensor of the gas detector may be affected by environmental factors (such as temperature, humidity, dust, etc.) during long-term use, resulting in a gradual decline in its performance.Regular annual inspection can find and correct the deviation of the sensor in time to ensure the accuracy of the test results.

2. Comply with regulatory requirements:

Many countries and regions have clear regulatory requirements for regular calibration and testing of gas detectors. For example, some industrial safety standards stipulate that gas detectors used for safety protection must be regularly calibrated to ensure that they meet safe use requirements.

3. Prevent security incidents:

Accurate gas detection is an important prerequisite for preventing safety accidents. If the sensor performance degradation leads to inaccurate detection results, it may delay the discovery and treatment of dangerous situations such as harmful gas leakage, which may cause serious safety accidents.
