Product details
The Wintact WT8811 is a portable 4 gas monitor that reads combustible gas (LEL), oxygen (O2), hydrogen sulphide (H2S) and carbon monoxide (CO) at the same time. As a compact multi gas detector it suits confined-space checks, plant rooms, sewers, workshops, farms and utility work, giving a clear view of all four readings on a colour screen with an English interface.
It runs on a 3.7 V 1800 mAh lithium-ion battery and weighs about 0.22 kg with the battery, so this portable gas detector clips easily into a kit bag. Please note it is a personal checking instrument and does not replace fixed gas alarms or a professional gas safety inspection.
