Original Factory Hydraulic Winch With Planetary Gear Box - Portable CH4,O2,CO,H2S multi-gas detector CD4 – Topsky
Original Factory Hydraulic Winch With Planetary Gear Box - Portable CH4,O2,CO,H2S multi-gas detector CD4 – Topsky Detail:
Applications:
CD4 portable Multi-gas detector is an intrinsically safe and explosion-proof instrument and is designed to deter the gases. It can simultaneously monitors up to four atmospheric hazards including carbon monoxide (CO), oxygen (O2), combustible gas (%LEL), and hydrogen sulphide(H2S). Compact and lightweight, CD4 portable Multi-gas detector activates audible, visual and vibrating alarms in the event of a low or high alarm condition.
CD4 portable Multi-gas detector is unparalleled in its versatility, capability and overall value. Water-resistant line of portable gas detectors has transformed the market with its matchless array of features.
It is used at the underground coal mine and mine safety inspection mainly. Certainly, it is also applied to fire fighting, confined space, chemical industry, oil and all kinds of environment that needed to measure the hazardous and toxic gases
Structure
CD4 adopts natural diffusion sampling method.Measured value is expressed as a percentage volume with three
effective reading which can display positive or negative value.Resolution respectively CH4 not less than 0.01% ,
oxygen 0.1% O2, H2S 1 x 10-6 and CO 1 x 10-6.It is with sound and light alarm and alarm self-check function.When
limit of methane concentrations over measurement range, measurement instrument has the function of protecting
carrier catalytic element, and are keeping the indications of the tester overrun
