Compact Multi-Gas Warning & Measuring Instrument (Ex)
Sewerin’s EX-TEC PM 5xx and EX-TEC PM 400 are rugged, explosion-proof mobile gas detectors engineered to protect utility and industrial professionals from hidden atmospheric hazards. The EX-TEC PM 5xx series serves as an all-in-one multi-gas powerhouse, capable of simultaneously monitoring up to five gases to pinpoint leaks and assess explosion risks with absolute precision. It features intuitive one-handed operation and a razor-sharp, sunlight-readable display to ensure maximum efficiency during demanding field operations.
Meanwhile, the highly adaptable EX-TEC PM 400 is a compact warning device that detects up to four toxic or flammable gases, delivering instant visual and acoustic alarms the second danger arises.
