Multi channel Gas monitor

This is world’s most compact, light weight, Micro controller based Multi channel Gas monitor with Individual Display. Flameproof version of TM-800/1600 is special developed and designed to meet industry requirement of Gas Monitors that need to be mounted in Hazardous area (Explosion/ Flame proof locations). These Monitors are enabling customer to save huge amount of money in Cable and Cabling cost. These models not only provide Gas reading for each channel but they also have Relay contacts and RS-485 output for external Audio-visual Alarms or for Data Loging respectively. Magnetic Key operated procedure provides ease of 1st time programming and routine calibration and maintenance. Flameproof models are available for Gas group IIA-IIB or for IIC. All the Explosion proof versions are PESO/CMRI/ERTL(E) approved
