Compur Monitors Gas Generator – Bump Tester for Gas Detectors

Personnel working in chemical plants protect themselves with personal gas detectors from gas exposure. Gas leaks are very unlikely to occur, so the gas detector will always display „0“.

An instrument displaying zero can do so for two reasons:
a) The concentration is zero.
b) The instrument is defective.

For good reasons a daily check of the instrument is mandatory. It would be too time – consuming to perform a complete calibration every day. The daily functional test with the gas generator makes sure that no instrument failure caused by abuse or wear and tear will go unnoticed. To perform a test, it is sufficient to expose the sensor to a short puff of gas and see if the instrument gives an alarm. To make this test as fast, easy and cheap as possible, no accurate gas concentration is used, but approximately twice the value of the alarm threshold.

The gas generator stops gas generation after 10 seconds automatically. If the detector fails to alarm within this time interval it is not safe to be used. The amount of gas produced when activated is very small. Therefore no restrictions regarding transportation and storage of the gas generator apply.

The following errors are reliably recognised:

• Electronics defective
• Alarm transmitter defective
• Sensor defekt
• Sensor too slow

More safety and more user-friendliness is not possible!
