Infrared CO/CO₂ Analyzer

Infrared CO/CO₂ Analyzer

  • Product Number:LD-Q3
  • Product Difference:Measure the concentration of carbon monoxide and carbon dioxide in the air

Product Introduction

The Infrared CO/CO₂ Analyzer is a high-precision instrument developed by our factory for detecting toxic and harmful substances in public air spaces. Utilizing non-dispersive infrared technology, it measures carbon monoxide and carbon dioxide concentrations in the air. Featuring high measurement accuracy, extended service life, and minimal cross-interference, it is an essential instrument in environmental monitoring and occupational health surveillance. This analyzer is widely used in environmental protection, environmental monitoring, health supervision, occupational health, disease control, and research institutions.

Product Features

  • Features an Android operating system with a 7-inch touchscreen display for enhanced real-time human-machine interaction.

  • Equipped with high-precision infrared sensors for superior measurement accuracy, rapid response times, and minimal warm-up periods.

  • Offers extensive storage capacity, capable of retaining over 100,000 data entries.

  • Supports both nitrogen zero calibration and catalytic zero calibration methods.

  • Built-in thermal printer for immediate data printing upon test completion.
