GTR-210 – ADOS

Gas transmitter with LCD, for different gas types

The gas transmitter ADOS GTR 210 is suitable for continuous measurement of gases in normal areas and areas where there are risks of explosion.

Available basic versions:
– EX-version: with current interface 4-20 mA
– Standard: 4-20 mA or LON®-4-wire techniques
– Comfort: 4-20 mA, with additional changeover contacts for alarms and failure

By employing 6 different types of sensor, noxious, explosive and non-combustible gases and vapours can be measured.

Display of the measured gas concentration and the adjustable alarm thresholds, are shown on a multi-colour graphic display. The keyboard input is by way of a touchpad.

A current signal is generated that is proportional to the measured concentration of gas, which is transmitted to an evaluation unit placed in a safe area, away from any dangers of explosion.

The type test of the explosion-protected gas transmitter, is completed by the DEKRA.
