Infrared carbon dioxide analyzer

Infrared carbon dioxide analyzer

    Infrared carbon dioxide analyzer is based on the infrared absorption principle, there is no abrasion on the measurement part thus no need to maintain. It is of good selectivity to the tested gas. The built-in temperature compensation sensor can reduce the error from temperature change on the measurement.

Infrared carbon dioxide analyzer is used for welding and cutting proportional gas.

Infrared carbon dioxide analyzer main features:

1.Friendly communication menu makes the operation visual and simple;

2.Long calibration interval cycle, high accuracy and reliable stability;

3.Function of storing 5000 history data allows users to look through the historic data at any time;

4.With the standard RS232(default)or RS485 communication port carried by it,the analyzer can do bidirectional communication with the computer;

5.The installation mode of frame mount makes it easy and convenient to install;

6.With power supplied at a wide range, the influence from mains fluctuation on the analyzer can be eliminated;
