Q45S Wet H2S Gas Detector
Brand: Analytical Technology IncThe Q45S/87 Wet H2S Transmitter is a microcomputer-based instrument for monitoring the concentration of a hydrogen sulfide gas in wet scrubber outlet vents or scrubber inlet ducts saturated with water vapor.
The system consists of three parts, a Monitor assembly containing an LCD display, analog outputs, and alarm functions.
A special H2S sensor with duct insertion holder designed for operation in condensing gas streams; and an optional air-purge system to periodically remove any water droplets that might accumulate on the sensor and cause slow response.
When air-purge system is ordered a system mounting plate is provided for mounting both transmitter and air purge system in the same location.
