Robust, compact and lightweight, it can detect up to four harmful gases in a row
With its many benefits, this instrument is a sought-after multi-gas detector around the world, and is your trusted companion in hazardous environments -- without the need for heavy equipment.
In addition, it is the only IP68-rated multi-gas detector with unrivaled water resistance – water resistance for up to 45 minutes at a depth of 1.2 meters. So you can use it in a wide range of harsh environments with confidence. The following two detectors have batteries that can run continuously for up to 18 hours, are operated at the touch of a button, and have undergone rigorous quality testing by Honeywell:
• Honeywell BWportableMCXL 4-in-1 gas detector: 1-year warranty.
• Honeywell BWportable MCX3 4-in-1 gas detector: 2-year warranty with a new oxygen sensor and an overall life expectancy of up to five years.
• We use unique advanced technologies to ensure safety, compliance, and productivity
• Advanced technology, reliable battery performance
• Small, thin, and easy to use, no professional training required
• Complete compliance verification with IntelliFlash flashing lights for an easy glance
