Analytical Technology Wet H2S Gas Detector, Q45S
The 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.
Features
  • Special Wet H2S Sensors designed to operate in condensing gas streams
  • Automatic Sensor Air Purge
  • Two Internal Alarm Relays
  • LCD Display
  • Internal Data Logger that stores up to 10 days of data at 1 minute storage intervals
  • Output Simulation
  • Weather-proof Nema 4X Enclosure
