Description
E4000 is a portable model with multiple gas detectors. It can continuously measure the concentrations of up to four combustible gases, oxygen, and toxic gases in the surrounding environment, and issue an alarm when the gas levels are abnormal.By adopting interchangeable smart sensor module, it can be made for detecting 2 gases, 3 gases and 4 gases.
It is applicable to explosion-proof places: teelworks, petrochemical plant, oil industry, shipbuilding yard, sewage treatment plant, mine, power supply works etc.
