The Honeywell 3000 MkII and MkIII gas transmitters provide comprehensive monitoring of toxic and oxygen gas hazards in potentially explosive atmospheres. The MkII has a flameproof housing with intrinsically safe sensor connection for Zone 1 applications; with optional remote mounting kit, the sensor can be used in Zone 0. The MkIII is fully intrinsically safe for Zone 0 applications.

Both are low-power, loop-powered 4-20 mA devices for new and retrofit installations. An easy-to-read LCD and intuitive interface allow user configuration. Fault diagnostic software and programmable calibration periods simplify maintenance. Intrinsically safe smart sensors are pre-configured and hot-swappable without removing power. Remote sensor mounting kit allows placement up to 50ft from the transmitter.

Surecell electrochemical sensors are ideal for hot and humid environments with Reflex sensing element verification diagnostics. Applications include oil and gas terminals, refineries, chemical plants, power generation, and wastewater treatment.
