TDLAS O2 Sensor

Gasboard-2510 oxygen sensor can give accurate oxygen concentration in real time.By adopting TDLAS (Tunable Diode Laser Absorption Spectroscopy) technology, Gasboard-2510 oxygen sensor  provides unparallel reliability with fast response feature for oxygen measurements. Gasboard-2510 oxygen sensor could reach measurement range of 0%~100% level with resolutions up to 0.01% to realize high accuracy and excellent repeatability. An auxiliary carbon dioxide sensor can also be incorporated into the O2 measurement bench for CO2 measurement. It is also compatible for other gas measurements by changing the light sources. Gasboard-2510 oxygen sensor can be widely applied for anethesia, medical oxygen monitoring, cardio fitness test, etc.
