Reliable monitoring for small hydrogen leaks in a variety of industrial and commercial facility environments is now available with the TS4000H Intelligent Hydrogen Gas Detector from General Monitors, which accurately detects hydrogen at 0-500 ppm levels.

The TS4000H Gas Detector continuously monitors for hydrogen.  It features a precision electrochemical hydrogen sensor that has a T90 response of under 30 seconds and minimal zero shift across its operating environmental conditions. Furthermore, it is unaffected by short-term (≤ 2.5 min) exposure to hydrogen concentrations up to 50% LEL.    
    
The TS4000H Detector features a sophisticated design with many advanced functions, including 4-20 mA output, 8 amp relays, HART or Modbus communications, and a 3-digit LED display that displays gas concentrations in ppm.  The system also displays fault codes for troubleshooting and provides complete status to the Control Room.  

All of the electronics are contained within an explosion-proof housing so that gas sensor information can be processed at the sensor site.  The gas sensor may be remote mounted up to 2000 feet (610 meters) away from the electronics.

The interface module’s galvanically-isolated, intrinsically-safe design also supports sensor field replacement without special tools or hot work permits. The TS4000H detector is easy to install and calibrates by activating a magnetic switch and applying gas. 
Process engineers who need to protect people, equipment, and the environment will find the TS4000H hydrogen sensor well suited for a broad range of industries where hydrogen gas leaks are a hazard. For worldwide application, the detector complies with ATEX, CSA, CE, GOST, and is certified for use in SIL 2 environments.
  In addition to monitoring for low hydrogen levels, the TS4000H can be configured to detect a variety of other toxic gases including: ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen chloride
