The TS4000H Intelligent Toxic Gas Detector from General Monitors is designed to deliver accurate ammonia detection and protection. The TS4000H Toxic Gas Detector monitors ammonia in the 0-50 or 0-100 ppm ranges. Its precision electrochemical sensor has little to zero drift across its operational environmental conditions and one of the fastest responses in the market, with a T50 response of less than 15 seconds and a T90 response of less than one minute. The TS4000H measures NH3 to ±5 ppm or ±10 per cent of reading, whichever is greater. The TS4000H features advanced functions like HART, event logging, and support of asset management software. The system also displays fault codes for troubleshooting and provides complete status to the control room. All of its electronics are contained within an explosion-proof housing so that gas sensor information can be processed at the sensor site.
