Detailed Product Description

Portable Gas Detector 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.

Portable Gas Detector Sensor Construction

Electrochemical sensor has two or three electrodes in contact with the electrolyte, and occasionally four electrodes. The typical electrodes are composed of a large surface area noble metal and a porous hydrophobic membrane. The electrodes and electrolyte are in contact with the surrounding air and are monitored by the porous membrane. Mineral acids are generally used as electrolytes. However, some sensors also use organic electrolytes. The electrodes are generally placed in a plastic box with gas inlet holes and electrical contacts.
