TDLAS301 Methane Laser Sensor with High Measurement Accuracy and Fast Response for Continuous CH4 Detection

The TDLAS301 module utilizes Tunable Diode Laser Absorption Spectroscopy technology with a narrow-linewidth single longitudinal mode tunable laser. Integrated with a cross-interference elimination algorithm, it effectively avoids background gas interference while delivering high measurement accuracy, fast response, and excellent stability.

Featuring refined temperature and pressure compensation, this module maintains reliable performance in harsh environments including high temperature, high pressure, and corrosive conditions. Its robust design enables continuous methane (CH₄) concentration detection across diverse industrial applications.

• Real-time online detection with rapid measurement speed and short response time
• Advanced cross-interference elimination algorithm prevents background gas interference
• Precision temperature and pressure compensation enhances stability and minimizes environmental effects
• Designed for operation in extreme conditions including high temperature, pressure, and corrosive environments
• Long service life with minimal maintenance requirements across multiple industrial applications

The module employs a tunable diode laser as its detection light source. By modulating the laser's injection current, the wavelength scans across the target gas's characteristic absorption lines. Gas concentration is determined through precise analysis of laser absorption spectrum variations.
