The standard gas detector system consists of a compact electronic module housed in a Weatherproof or explosion proof Metallic or Polyester box with an application specific sensor. Gas detector state of the art transmitter is carefully designed with and manufactured with Industrial grade Components for reliability accuracy and long life. gas detector is certified for use in hazardous areas Class 1, Division 1, Group B, C & D. (IIA, IIB or IIC) apart from being available in weatherproof Enclosure. Transmitters are equipped with micro controller and are heavily featured with self-diagnostics, Auto calibration (in case of toxic, O2, combustible gases only) through embedded Software, can be done at site. RS 232/485 output with baud rates of 2400 bps is available as an option
