The Tuoan TA-DLAS online laser gas analyzer adopts semiconductor laser spectral absorption technology DLAS, which is essentially a spectral absorption technology that obtains gas concentration by analyzing the selective absorption of laser by gas molecules, especially for online measurement of gas concentration and other parameters in harsh environments such as high temperature, high pressure, high dust, and strong corrosion.
Online laser gas analyzerTA-DLAS has fast response speed, high reliability, and good stability. Easy maintenance and low operating costs. Capable of rapid, accurate, and real-time measurement of various industrial process gases, environmentally friendly exhaust gases, and other process gases.
Application areas: process analysis, smelting, chemical industry; Monitoring of CO concentration in flue gas, etc.
Product advantages:
1. No need for a sampling preprocessing system to overcome the problem of tar clogging probes;
2. Strong anti-interference ability, not affected by background gas cross interference and dust, gas parameters, etc;
3. Has good adaptability in harsh measurement environments such as high temperature, high dust, high moisture, high corrosiveness, and high flow rate;
4. Simple construction, no movable components, no loss components;
