Key Features

• With high selectivity, TDLAS is a high-resolution spectroscopic technique. Due to the unique “fingerprint” characteristics of molecular spectra, measurements are not interfered with by other gases, a feature that offers significant advantages compared to other analytical methods.
• With broad applicability, TDLAS technology effectively measures all active molecules that absorb in the near-infrared region, covering virtually all major gases used in engineering analysis.
• With high versatility, TDLAS technology offers advantages such as rapid response and high sensitivity. When combined with a long optical path gas cell, it enables measurement of trace-level gases at the ppb level.
• Continuous monitoring, ultra-fast measurement response.
• Dual range design, wide measurement range, ultra-low detection limit.
• Enhanced Heliotrope light cell structure for ppb-level measurements.
• Half-year calibration, easy maintenance, no consumable costs.
• Special coating to effictively minimize the interataction, absorption, and the chemical reaction of the measured gas on the pipe wall.
