Continuous monitoring for toxic gas

The Det-Tronics GT3000 line of electrochemical fixed-point toxic-gas detectors is designed and engineered to provide continuous monitoring of the atmosphere for potentially hazardous toxic gas leaks or oxygen depletion. Both explosion-proof and intrinsically safe models are available.

The GT3000 Toxic Gas Detector is not available for sale in the European Union (EU) and the United Kingdom (UK).

The GT3000 family currently includes sensors that detect each of the following gases in various concentration levels:

hydrogen sulfide (H2S) - certified SIL 2 capable

hydrogen (H2)

oxygen (O2) - certified SIL 2 capable

carbon monoxide (CO)

nitrogen dioxide (NO2)

ammonia (NH3)

chlorine (Cl2)

sulfur dioxide (SO2)

A complete GT3000 detector consists of a transmitter (GTX) and a sensor module (GTS). The transmitter generates a 4-20 mA output signal with HART that is proportional to the concentration of the target gas and corresponds directly to 0-100% full-scale output.
