New Gas Generator to check personal Gas Detectors
A 100% Test in just 10 Seconds
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. Local regulations allow calibration intervals of up to six months.
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 quality criterion for the detector is not reaching a certain value, but the response time: A good sensor is also a fast sensor. So 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. Thus the generator test reliably indicates the following potential errors:
- Defective electronics
- Alarm buzzer or lamp defective
- Sensor defective
- Sensor too slow
- Sensor not sensitive enough
