Closed-path TDLA gas sensor

Sensor name: 

Closed-path TDLA gas sensor


The closed-path tuneable diode laser analyser (TDLA) is a stand-alone sensor module that performs real-time measurement on gaseous ammonia (NH3) and carbon-dioxide (CO2) concentrations based on tuneable diode laser absorption spectroscopy. Thanks to an extremely high laser resolution, the sensor exhibits high precision and selectivity towards the target gas. The compact design and light weight of the sensor make it well suited for portable applications.
