[R&D Background]

In the context of current environmental protection and gas monitoring, the emission and concentration of nitrous oxide in the atmosphere have become significant concerns. Nitrous oxide is an important gas in agriculture, industry, transportation, and other fields, and its emissions are closely related to environmental quality and air pollution. To accurately monitor the concentration of nitrous oxide in the atmosphere, Ningbo Haierxin Optoelectronics Technology Co., Ltd. has launched the Xinyong Smart Measurement · HT8500 Atmospheric Nitrous Oxide Laser Open-Path Analyzer.

[Product Introduction]

The HT8500 Atmospheric Nitrous Oxide Laser Open-Path Analyzer is independently developed, produced, and sold by Ningbo Haierxin Optoelectronics Technology Co., Ltd. It is an innovative domestic product under the "Xinyong Smart Measurement" brand, offering high precision and high sensitivity, specifically designed for real-time monitoring of nitrous oxide concentration in the atmosphere. Utilizing quantum cascade laser technology and signal processing algorithms, it can quickly and accurately measure nitrous oxide concentration, providing reliable data support for environmental monitoring and air quality management.

The instrument employs quantum cascade laser technology, using two highly reflective mirrors in the atmosphere to perform multiple reflections of mid-infrared laser light, achieving an effective optical path of tens of meters. It measures the weak absorption of mid-infrared laser energy by the target gas at characteristic absorption peaks and inverts the concentration of trace gases through real-time integration of the absorption peak spectral curve.

[Core Technologies]

Quantum Cascade Laser Technology: The HT8500 utilizes quantum cascade laser technology, leveraging the principle of nitrous oxide molecules absorbing light energy under laser radiation at specific wavelengths to achieve non-contact measurement of nitrous oxide concentration.

High-Resolution Spectroscopy: This technology enables the acquisition of high-resolution spectral data, thereby improving measurement accuracy and sensitivity.

Signal Processing Algorithms: Built-in signal processing algorithms accurately analyze spectral data, converting it into nitrous oxide concentration values while eliminating the effects of interfering factors.
