High precision LEL gas detection device

Stand Alone Detectors. The stand-alone detection units can be equipped with up to two sensors, for example, (1) built-in CO sensor and (1) remote sensor that can be for any one of the three gases listed, namely, CO, NO2 or Combustible gas (CH4 C3H8).

The S4000TH Intelligent Gas Sensor is a microprocessor-based transmitter designed for use with General Monitors' thin film metal oxide semiconductor (TFMOS) sensors to detect H2S gas. The unit features one person calibration and can virtually self-calibrate by simply activating a magnetic switch and applying gas.

The gas monitors come with an integrated LCD display, RS232 and RS485, 0-5V outputs and audible alarm, which can be configured to a user defined set point. They also come with a 12VDC power supply that plugs directly into the monitor and mains power allowing for easy set up and installation.
