- 产品名称：GTR 196气体传送器
- 产品定货号：MR-00804-00
The gas transmitter ADOS GTR 196 is suitable for continuous measurement of gases in normal areas and areas where there is a risk of explosion.
By employing 5 different types of sensor, noxious, explosive and non-combustible gases and vapours can be measured.
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 KEMA.
Test certificate: KEMA 03 ATEX 2403 X
Degree of protection: II 2 G, Ex demb [ia] IIC T6
