EXPEC 1680

Instrument Introduction

For EXPEC 1680, the Fourier infrared spectrophotometry principle and the multiple resolution correction method are adopted based on the feature that different gases have different characteristic absorption in the range of infrared spectroscopy, enabling the qualitative and quantitative measurement of gases. The instrument can be used to monitor the smoke of stationary pollution sources from coal-fired/gas-fired power plants, waste incineration plants and steelworks, and also used for the rapid emergency detection of inorganic gases and some organic gases in the ambient air.
