Laser Trace Moisture Gas Analyzer

Product Overview

The Laser Trace Moisture Gas Analyzer uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology and is specially designed for precise gas moisture measurement. It provides real-time readings of moisture volume fraction and dew point. The analyzer offers high precision, fast response, high sensitivity, and long-term stability, making it ideal for natural gas liquids (NGL) recovery units, low-temperature LNG processes, and other industrial gas applications. The device supports multiple signal outputs and communication interfaces, and features explosion-proof construction and high protection ratings for safe operation in harsh industrial environments.

Technical Principles

The instrument employs TDLAS technology to measure the absorption of laser light at specific wavelengths by water molecules in the gas. This enables high-precision, online measurement of gas moisture and dew point with minimal interference from background gases. The fast response time and long-term stability ensure reliable monitoring under continuous operation.
