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
