GasTech Australia has used the latest electrochemical technology for the detection of a large number of gas in ppm and ppb levels.
The GasTech’s unique CO sensor has a built in generator cell which will generate a small amount of interference gas over the sensor giving the user a confidence check that the sensor and system is operating as required.
The Built In Test (BIT) is simply activated by placing a magnet between “GAS TYPE” and “RANGE” on the front cover until the green LED starts to brighten. If the BIT is successful and everything is working correctly the green LED will change to Red for a few seconds then returns to Green for normal operation. This gives the user indication that the BIT was successful. Once the test is complete the green LED will dim and the sensor will return to normal operation within 60 seconds. This feature is only compatible with our CO sensors.
