H2S Detector – S4000TH

H2S Detector – General Monitors S4000TH Intelligent Sensor

The Model S4000TH Intelligent H2S Detector is a microprocessor-based transmitter designed for use with General Monitors’ thin film metal oxide semiconductor (TFMOS) sensors.

This unit features one person calibration and can virtually self-calibrate by simply activating a magnetic switch and applying gas. It is designed to detect hydrogen sulfide in parts per million (ppm) levels and provide status indication and alarm outputs.


  • Meets stringent ISA S92.0.01, Part 1, 1998 performance standard set by ISA and approved by FM
  • Event logging stores fault, gas check, calibration, and alarm event history
  • HART and Modbus communication provides complete status and control capability in the control room
  • Industry standard 4-20mA output for remote alarm and fault indication
  • Warning, alarm & fault relays provides local alarm capability
  • Calibration, calibration check, setup mode simplifies operation and maintenance
  • Remaining sensor life indication reduces downtime by providing an estimate of remaining sensor life
