Most fixed Gas Detection Units (GDUs) should be calibrated every 6 months. In harsher or higher-risk environments, calibration may be needed quarterly.
Yes, regular calibration is necessary because sensors can drift over time and exposure to poisons or inhibitors can affect readings.
GDUs can detect gases such as carbon monoxide (CO), hydrogen sulphide (H₂S), oxygen (O₂), methane (CH₄), and other flammable or toxic gases, depending on the sensors installed.
A common standard is that the detector must register at least 50% of the calibration gas concentration during a bump test.
Bump testing is recommended every 3–6 months for electrochemical sensors, with full calibration at least annually or if bump testing shows the sensor is out of spec.
Yes, and the frequency depends on risk level. Best practice is to bump test before each use and calibrate regularly based on risk and manufacturer guidance.
Most gas detectors last about two to five years, but this can vary with model, usage, and maintenance.
Calibrate before first use and then at intervals not exceeding 6 months. A daily bump test is recommended to check sensor and alarm functionality.
