Product introduction

 

瓦斯抽放综合参数测定仪是专门用于测量瓦斯抽放管道中各测点的瓦斯浓度、流量、差压、负压、温度、氧气、一氧化碳等参数的便携式智能精密仪表,具备不用通过法兰连接,直接插入管道测量的优点,具备频率输出和RS485接口,可以与瓦斯监控系统或瓦斯抽放系统相连接。 CJZ7 Gas Drainage Comprehensive Parameter Detector is a portable intelligent precision instrument specially used to measure gas concentration, flow rate, differential pressure, negative pressure, temperature, oxygen, carbon monoxide and other parameters at various measurement points in a gas drainage pipeline. It has the advantages of blue connection and direct plug-in pipe measurement. It has frequency output and RS485 interface, and can be connected with gas monitoring system or 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.

具备数据存储、数据趋势图、数据浏览的功能。 CJZ70 has the functions of data storage, data trend graph and data browsing.

Product Features

u Measurement types: gas concentration, flow rate, negative pressure, differential pressure, temperature, oxygen, carbon monoxide, a total of 7 parameters

u Directly inserted into the pipe for measurement: no additional flange connection is required, which ensures the convenience of operation

u Data output diversification: comes with frequency output and RS485 output to connect with the gas monitoring system or gas drainage system to transmit the extracted data to the ground data center

u easy to carry: weight less than 4.6kg

u Suitable for various pipe diameters
