Oxygen analyzer GasTDL-3100 (Single Ended)

carbon dioxideCOCH4

Overview
GasTDL-3100 is a single-ended in-situ laser gas analyzer designed for real-time measurement of process gas concentrations in industrial applications.

Based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology, it enables highly selective and accurate detection of key process gases including O2, CO, CO2, and CH4. The in-situ measurement method performs direct gas analysis without the need for complex sampling or gas pre-treatment systems, providing fast real-time measurement. With an internal reference gas cell locking the laser to the target absorption line, GasTDL-3100 ensures stable and reliable measurement under changing process conditions.

The single-ended design simplifies installation by eliminating on-site optical alignment, while the rugged construction allows reliable operation in harsh environments with high temperatures, heavy dust, and corrosive gases.

GasTDL-3100 is widely used for safety monitoring and process optimization in the oil & gas, chemical, metallurgy, and power & energy industries.

Features

• Highly Selective TDLAS Technology: Accurate target gas measurement without cross-interference from background gases.
• Direct In-Situ Gas Measurement: No sampling or gas conditioning systems required, enabling fast real-time analysis.
• Built-in Reference Gas Cell: Continuous locking of the laser to the target absorption line for long-term measurement stability.
• Single-Ended Design: No optical path alignment required, simplifying installation and commissioning.
• Rugged Industrial Construction: Reliable operation in harsh environments with high temperature, heavy dust, and corrosive gases.
