1,Overview

The CJZ300 comprehensive parameter measuring instrument for gas extraction is a portable intelligent precision instrument specifically designed for measuring various parameters such as gas concentration, flow rate, differential pressure, negative pressure, temperature, oxygen, and carbon monoxide at each measurement point in the gas extraction pipeline. It has the advantage of not requiring flange connection but allowing direct insertion into the pipeline for measurement. It features frequency output and RS485 interface, and can be connected to gas monitoring systems or gas extraction systems. The instrument has the functions of automatic data protection upon power loss and automatic power-off in case of low voltage.

The CJZ300 also has the functions of data storage, data trend graph, and data browsing.

2,Features

The most types of measurements: gas concentration, flow rate, negative pressure, differential pressure, temperature, oxygen, carbon monoxide, totaling 7 parameters.
Direct insertion into the pipeline for measurement: No additional flange connection is required, ensuring the convenience of operation.
Diversified data output: Equipped with frequency output and RS485 output, enabling connection with gas monitoring systems or gas extraction systems, and transmitting the extracted data to the ground data center.
Portable: Weight less than 4.6kg.
Suitable for various pipe diameters.
