LGT-300 One-Side Installation Laser Gas Analyzer

Overview

LGT-300 laser moisture analyzer is a high precise analyzer for gas measurement, developed based on tenable diode laser absorption spectroscopy. One-side mounting installation is much easier than cross-stack.

By using a tunable semiconductor laser, the LGT series laser gas analyzer scans the specific absorption lines of the measured gas(no background gas) to get the second harmonic of the gas. Through processing and analyzing the second harmonic and the broadening information of the gas, the concentration of the gas is obtained.

Features Of LGT-300 One-Side Installation Laser Gas Analyzer


• Non-contact optical measurement, low drift, and long service life.
• One-side installation, no complex adjustment of the optical path required.
• Reference gas cell adopted; online calibration; no disassemble needed
• "SIngle line spectrum" technology, free from the interference of background gas
• In-situ measurement, no sample conditioning required and avoiding the problems that sample is absorbed during the conditioning process, blocking, unit damage and etc.
• Low maintenance cost
