Product Introduction

The WEI-2000 flue gas analyzer (conventional range) is a gas analysis product independently developed by our company for environmental online monitoring and industrial online analysis. This analyzer is based on ultraviolet differential absorption spectroscopy technology and can measure gas concentrations such as SO2, NO, O2, CO, CO2, etc. It has the characteristics of high measurement accuracy, strong reliability, low operating cost, fast response time, large range span, and wide application range. All indicators reach or exceed similar products at home and abroad.

Product advantages

Using ultraviolet differential absorption spectroscopy technology and chemometric algorithms to detect low detection limits and small temperature drift;
It can directly measure NO and NO2 to obtain NOx without the need for a NO2 to NO converter;
Not affected by factors such as particulate matter and moisture;
High reliability without optical moving parts, and on-site vibration has no impact on measurement.
