The Model 1400 H2S Gas Detector System produced for the U.S. Navy (NAVSEA) provides a fixed capability to detect Hydrogen Sulfide gas in shipboard spaces containing sanitary waste equipment -- in particular the Collection, Holding and Transfer (CHT) rooms. Each Model 1400-00 Hydrogen Sulfide (H2S) Gas Detector System consists of one Model 1400-04 Control Unit and four Model 1401-05 Detector Heads.
Each detector head continuously monitors the concentration of H2S over the range of 0-100 parts per million (ppm). Sensor outputs are sent to the control unit via separate 4-20 mA channels. The control unit provides a Warning signal and indication when one or more of the detector heads indicates H2S concentrations above 10 ppm, and it provides a Danger signal and indication when concentrations above 50 ppm are detected.
The stainless steel control module includes a display panel with LED indicators for sensor and system status. Each detector head is in a stainless steel housing with a fully encapsulated electronic transmitter assembly and electrochemical sensor. The Model 1400 has been designed, tested and approved to meet MIL Spec requirements for shipboard use.
