Laser Gas Detection TDLS Technology 【English】

Leister Corporate, Axetris, Laser Gas Detector 

Axetris uses proprietary technology-enhanced TDLS for gas detection. A 0.05 nm narrow bandwidth diode laser beam is used to scan across an absorption band of the target gas, thus performing a high-resolution near infrared absorption measurement. 

Laser gas detection, based on Tunable Diode Laser Spectroscopy or TDLS, provides a valid solution to many challenges in environmental gas monitoring and process control. 

The TDLS technology offers unique advantages like:

• precise optical, contactless measurements

• excellent target gas selectivity

• sub ppm-level detectivity for gases such as CH4, NH3, HCl, H2O and CO2

• low cost of ownership

• high stability, reliability and availability in the field (no regular replacements / calibration needed)

Our laser gas sensing modules are a cost effective solution for OEM integrators active in emission control and environmental monitoring. It allows for simple integration due to its self-contained and standalone system design. It also offers hot-gas measurements up to 220°C, which provide a robust sensing solution for highly contaminated gas sample typically for SCR DeNOx and other industrial applications. With our gas sensing modules, we are able to cover a wide range of gas monitoring & detection applications in combustion control, leak detection, breath gas analysis, greenhouse gas monitoring, safety and many more.
