Tunable Diode Laser Absorption Spectroscopy Gas Analyzer(TDLAS)

Online-H2S-Gas-Monitor
Vasthi Instruments TDLAS VLGA – 8000 analyser is capable of analysing O2, CO, NH3, CO2, CH4, H2O, HCl, HF and other gases in various and complex conditions. The VLGA- 8000 laser gas analyser can be directly installed across stack, with the advantages of uncomplicated sampling, no pre-treatment system, simple construction and no moving parts. The analyser’s OLED screen benefits from low power consumption, a wide viewing angle, and excellent low temperature resistance, it can quickly respond to magnetic pen operation.
