Hainan Dingyan R&D and production of laser principle HF hydrogen fluoride gas concentration analysis and detection monitoring instrument

Note: Due to numerous configurations and different operating conditions and parameters, this price is for reference only. The specific price can only be determined after technical communication.

Product Overview:
The NK-TDLAS laser HF analyzer is based on the principle of tunable semiconductor laser absorption spectroscopy (TDLAS), which is currently one of the gas measurement methods. Our NK-TDLAS laser HF analyzer uses an imported laser light source and has the characteristics of high resolution, fast response speed, and long sensor life. The installation methods can be selected from extraction installation and in-situ installation, which can meet the requirements of process analysis and environmental monitoring under different working conditions.

Capable of online measurement of gas concentration and other parameters in various environments, especially harsh environments such as high temperature, high pressure, high dust, and strong corrosion, with accurate measurement, fast response speed, high reliability, and low operating costs. It has been widely used in fields such as petrochemicals, steel metallurgy, environmental protection, fertilizers, and pesticides.
