TS4000H intelligent hydrogen gas detector

The TS4000H intelligent hydrogen gas detector provides reliable continuous monitoring and accurately detects hydrogen at 0–500 ppm levels. It features a precision electrochemical hydrogen sensor that has a T90 response of under 30 seconds and experiences minimal zero shift across its operating conditions. In addition, it is unaffected by short-term (= 2.5 min) exposure to hydrogen concentrations up to 50% of the lower explosive limit (LEL). The detector has many advanced functions, including 4–20-mA output, 8-amp relays, HART or Modbus communications, and a 3-digit LED screen that displays gas concentrations in ppm. The system also displays fault codes for troubleshooting and provides complete status information to the facility’s control room. The sensor may be mounted remotely, up to 2,000 ft away from the electronics. The detector complies with ATEX, CSA, CE, and GOST standards, 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, hydrogen sulfide, nitric oxide, nitrogen dioxide, oxygen deficiency, ozone, and sulfur dioxide.
