【R&D Background】

As global climate change intensifies, the impact of greenhouse gas emissions and variations on the environment and climate becomes increasingly evident. In order to better monitor the composition and concentration of greenhouse gases in the atmosphere to support climate research and environmental protection measures, HealthyPhoton Technology Co., Ltd. has introduced the HT8830 All-in-one Portable GHG Analyzers.

 

【Product Introduction】

HT8830 All-in-one Portable GHG Analyzers (carbon dioxide, nitrous oxide, water vapor) is independently developed, produced, and sold by HealthyPhoton Technology Co., Ltd., representing a domestically innovative product. This series of instruments is designed based on quantum cascade laser technology, utilizing the "fingerprint" absorption spectra of gas molecules in the mid-infrared region. It uses semiconductor quantum cascade lasers (QCL) as light sources, allowing the laser to pass through an original mid-infrared enhanced optical cavity. The transmitted light is received by a mid-infrared photodetector, and the transmitted spectra are extracted and analyzed. This process accurately calculates the concentrations of the target greenhouse gases, enabling more precise, timely, and scientifically accurate measurements of target greenhouse gas molecules.

 

HT8830 All-in-one Portable GHG Analyzers achieves rapid and high-precision greenhouse gas measurements within a portable instrument case. It employs independent strong absorption spectral lines, eliminating cross-interference from other gas molecules. This series of gas analyzers can be powered by solar energy or lithium batteries, enabling fixed-point or mobile continuous observation of greenhouse gas concentrations.

 

【Core Technology】 QC Laser-based Sensing Technology(Infrared Laser Spectroscopy Detection)

Multi-component analysis technology: The HT8830  uses multi-channel gas analysis technology, allowing simultaneous measurement of multiple greenhouse gases.

Spectral absorption technology: The instrument uses spectral absorption principles, where a laser beam at specific wavelengths interacts with gas molecules to achieve non-contact concentration measurements.

Intelligent calibration algorithm: Built-in intelligent calibration algorithms accurately compensate for sensor drift, ensuring the reliability and accuracy of measurement results.

 

【Product Features】

1.Multi-component:

Target species: CO₂, N₂O, H₂O;

Accuracy is ensured by independent and strong absorption spectral lines in the mid-infrared band with no cross-interference.

2.Reliability:

Strong MIR absorption signals of gas molecules eliminate the need for an extremely long optical cavity, resulting in stable optics and highly reliable data.

3.Portability:

A waterproof, durable, and easy-to-carry casing based on high-strength ABS material.

4.Low power consumption:

Less than 100W power consumption that can be powered by solar panels or batteries for continuously uninterrupted operation.

5.Flexibility:

Support fixed-point or vehicle-mounted continuous automatic detection.
