MSA Ultima Xe/Xir Gas Detector

Feature & Principle

It is MSA Ultima X series fixed gas detector. Ultima Xe uses electrochemical sensor for oxygen and toxic gas monitoring. Ultima XIR adopts non-dispersive infrared technology to detect hydrocarbon combustible gas, immune to catalyst poisoning. It converts gas concentration signal to standard 4-20mA analog signal, and supports HART digital communication. Smart pluggable sensor allows replacement without power off. Built-in LCD display, status LED and multi-channel alarm relay. 316 stainless steel explosion-proof enclosure adapts to oil, chemical and refinery hazardous areas.
