Compact Area Monitors
mG-4000 monitors are compact detection instruments that accurately measure combustible gases, toxic gases and oxygen levels. Three Alarms, in-built hysteresis, universal power input, variety of Audio-visual alarm devices, 3 digit LED display, 1 digit Ch. No. display, variable ranges  LEL, Vol., ppmall these make this Monitor a power house of gas monitoring systems.

Simple and effective
The unit accurately displays measured gas concentration on a large 3 digit LED display. Compact and simple design facilitates easy doit- yourself type installation. Pre-calibrated Sensors allow direct commissioning without need of skilled manpower. Monitor is equipped with onboard relays for three alarm points. It also has one sensor fault relay output. These relays can be used to drive
external devices like strobes, fans, voice alarms, auto-dialers, etc.
