Gas Detectors

S4000CH Combustible Gas Detector

S4000CH Combustible Gas Detector

The S4000CH Intelligent Sensor is a microprocessor-based transmitter designed for use with General Monitors industry-leading catalytic bead sensors. It monitors combustible gases and vapors within the lower explosive limit (LEL) and provides status indication and alarm outputs. Complies with ANSI/ISA 12.13.01-2000 performance requirements for combustible gas detectors.
IR5500 Open Path Infrared Gas Detector

IR5500 Open Path Infrared Gas Detector

The IR5500 is an open path infrared (IR) gas detector that continuously monitors for flammable gas leaks over large open areas. It monitors in both the LEL-m and ppm-m ranges to detect both small and large leaks. The IR5500 offers the benefits of early detection with its high sensitivity to gas concentrations at the ppm levels.  This feature allows it to alarm faster than an LEL-only detector. Digital display and adjustable mounting arms ensure easy alignment. Factory calibrated for low-maintenance operation.
IR4000S Single-Point Gas Monitor

IR4000S Single-Point Gas Monitor

The IR4000S Single-Point Monitor is a display and user interface for the IR400 point IR gas detector. The monitor allows local calibration and displays gas concentration. Relays are optional. The relays provide output for Alarm, Warn, and Fault conditions.
IR4000M Multi-Point Gas Monitor

IR4000M Multi-Point Gas Monitor

The IR4000M Multi-Point Gas Monitor can be used as an integrated combustible gas detection system, with capacity to connect eight point IR or open path gas detectors and read their status with one command. The highest current % LEL among all connected detectors is shown continuously during normal operation. An extensive set of menus are easily navigated using a magnetic switch to request the status and configuration data stored by the IR4000M.
