Overview
Portable multi-gas detectors protect workers entering confined spaces and check for leaks and toxic atmospheres in plant rooms, tanks, pits and process areas. MEWOI's detectors are configured to order: you choose the gases and ranges, and the instrument is fitted with the matching sensor technology, whether electrochemical, catalytic combustion, infrared, thermal conductivity or PID photoionisation.
The MS104K is a fixed 4-in-1 detector for CO, H2S, O2 and combustible gas (LEL), the standard confined-space set. The MS400 takes any combination of one to four gases, and the MS500 five. The MS600 and PTM600 are portable composite analysers taking one to six gases, expandable to eight, for broader process and environmental monitoring. Temperature and humidity can be added as options.
