Product Introduction

HT8500 is based on the state-of-the-art Quantum Cascade Laser Absorption Spectroscopy (QCLAS) technology. The product relies on the laser beam’s multiple reflections between two high-reflection mirrors exposing to the atmosphere, creating an effective optical path-length of several tens of meters. The weak absorption of the laser energy at the spectral peak is extracted from the noise using phase-sensitive lock-in amplification of the modulated laser wavelength/amplitude signal. The trace gas concentration is retrieved based on HealthyPhoton’s innovative absorption spectral characterization algorithm.

HT8500 can be used for Eddy Covariance Flux studies. It can accurately quantify the net exchange flux of atmospheric nitrous oxide in various ecosystems.
