MAINTENANCE & ADVICE
MAINTENANCE
The service life of a gas detector depends heavily on maintenance.
Just as a car needs to have its oil level checked every x number of kilometers and its filters replaced on time, a gas detector also requires maintenance.
In most cases, maintenance is performed every six months (180 days). This includes calibration, bump testing, replacing filters, timely replacement of sensors, and verifying accurate readings for the specific gas being measured.
All information is documented in a certificate and maintenance report, ensuring that you and your employees can once again
Does your car get serviced on time? Apply the same principle to your gas detection device.

10 Tips for Using Gas Detectors
- Check the calibration sticker. The detector must be calibrated every 6 months.
- Bump the detector daily with the correct calibration gas.
- Turn on the gas detector in a clean environment so that it is properly calibrated when zeroing.
- Block the filter of a pumped detector at startup. The detector should trigger an alarm. If no alarm sounds, there is a problem and it must be checked.
- When using a suction hose, we recommend 4 seconds of suction time per meter for an accurate measurement. The sensor must also stabilize. Example: with a 5-meter hose, it is recommended to wait 20 to 30 seconds for an accurate result.
- Is the confined space containing less than 12% oxygen? Use an IR LEL sensor rather than a catalytic LEL sensor to ensure an accurate measurement.
- Wear the gas detector over your work clothes.
- Do not lower your device into the confined space using a cord or rope. Use a pump-operated device instead. You must always be able to read the measurements on the portable device.
- Do not use a lighter to check the operation of a LEL sensor. The sensor will be contaminated.
- If in doubt, seek advice from the appropriate personnel.
