Clairvoyance of gas drainage system

CJZ70 gas drainage comprehensive parameter tester is a portable intelligent precision instrument specially used to measure gas concentration, flow, negative pressure, differential pressure, temperature, oxygen, carbon monoxide and other parameters at various measurement points in the gas drainage pipeline It has the advantages of blue connection and direct plug-in pipe measurement, with frequency output and RS485 interface, and can be connected to a gas monitoring system or a gas drainage system. The instrument has the function of automatically protecting data during power failure and automatic power-off when the power supply is under voltage.

CJZ70 has the functions of data storage, data trend graph and data browsing.
