SPXCDULNG1 HONEYWELL

Product Overview

The Honeywell SPXCDULNG1 is an explosion-proof, fixed industrial gas transmitter kit configured explicitly for the detection of Hydrogen ($H_2$) gas leaks across a specialized measurement range of 0 to 1,000 ppm. Housed in a flameproof, epoxy-painted LM25 aluminum alloy enclosure featuring two 3/4-inch NPT conduit entries, it carries strict UL, cUL, CSA, and INMETRO certifications for Class I, Division 1 hazardous environments. The system relies on a high-stability electrochemical (EC) Surecell sensor cartridge and delivers real-time data using an industry-standard 4–20 mA current loop alongside Modbus RTU communications, backed by three built-in 5-amp power relays.
