XNXXSH1SS – Smart Sensor Cartridge for H₂S (Lo)
XNXXSH1SS is a Honeywell smart sensor cartridge designed for hydrogen sulphide (H₂S) low-range detection. It offers a selectable full scale from 10.0 to 50.0 ppm with a default 15.0 ppm range. The sensor delivers T90 response under 30 seconds and accuracy within ±0.3 ppm. This industrial-grade cartridge operates reliably from -40°C to 55°C. It is ideal for oil & gas, wastewater, and chemical plants.
