Instrument Series

It adopts micro-flow infrared technology to measure the CO,NO,SO2, UV DOAS technology to monitor NO,SO2. It not only has long life time  and high precision advantages but also solved the eliminate the impact of moisture on measurement values and effects of environmental temperature.

Pre-treatment and Sampling System

The professional pretreatment and sampling device can ensure the whole system works stability and accurate for long time.

PLC Controller

It can achieve complete automatically sampling gas, back blowing, alarm and other functions, meanwhile it can monitor automatic for 24 hours to reduce labor costs.

Data Transmission Interface

Measurement data via RS-232/RS-485 and 4-20mA output interface transmit to the DCS system, in order to realize remote.
