Cross Duct Gas Analyzer

The VGA-1000 is a flameproof tunable laser gas analyzer based on TDLAS technology that can in-situ analyze 02, CO, NH3, CO2, CH4, H2O, HCI, HF, and other gases in various complex conditions. It consists of a transmitter, receiver, and connection box. The transmitter drives the tunable diode to emit a laser of certain wavelengths, which passes through the environment to be measured, then reaches the receiver. The receiver performs photoelectricity conversion, signal processing, and spectrum data analysis to obtain the measuring result. The connection box contains a 1/0 interface, making the connection of the power cable and signal cable convenient.


  • Easy optical path adjusting, XY direction non-compiling adjusting.
  • Small drift, long maintenance period, drift
  • "Single line" spectrum technology, free from the interference of background gas.
  • Integrated structure design, high stability, and reliability.
  • Integrated flameproof structure, consuming less purge gas compared with positive-pressure model ' In-situ measurement without pretreatment system avoids adsorption, blockage, and damage reduces the cost.
