The Q-Test allows gas testing of Gas-Pro monitors fitted with flammable oxygen, carbon monoxide, hydrogen sulphide, carbon dioxide, ammonia, or sulphur dioxide sensors. As configured in the Gas-Pro, Q-Test can bump multiple gases in up to two groups.

Gas (bump) testing exposes each sensor to a known gas concentration to ensure it responds correctly.

Regularly gas-testing portable monitors ensures that the sensors are performing correctly and allows users to recognise alarms (visual, audible and tactile).

Passing the test promotes confidence while failing it signals the need for calibration or, in some instances, service.

When used with a trigger regulator, the cost of gas testing is low, taking only 12 seconds to complete a 5-gas test (CO, H2S, O2, CH4, CO2).
