LY-NDIR Non-Dispersive Infrared Multi-Gas Measurement Module (CO, CO₂, CH)

Module Introduction

The module is specially developed for vehicle emission analysis instrument, and can simultaneously measure HC, CO and CO2 We can also customize the functions of measuring N2O, SO2, NO, CH4, hydrocarbons, other VOCs, malodorous gases and other infrared absorption gases according to customers’ requirements. The measurement range is from ppm to % level.

 

Principle

The module is specially developed for vehicle emission analysis instrument, and can simultaneously measure HC, CO and CO2 We can also customize the functions of measuring N2O, SO2, NO, CH4, hydrocarbons, other VOCs, malodorous gases and other infrared absorption gases according to customers’ requirements. The measurement range is from ppm to % level.

Features
  • Adopting a pulse modulation infrared light source, without the need of mechanical chopping modulation;

  • Adopting-multi-channel pyroelectric detector,which provides higher sensitivity;

  • Constant temperature control ensures good stability;

  • Simultaneously detect CO, CO2, HC;

  • Self-developed algorithm provides stronger anti-interference capability;

  • The mechanical structure can be customized according to requirements.

 

Applications
  • TOC detection of water quality

  • Ambient air analysis

  • Indoor air quality monitoring

  • Analysis of waste gas from pollution sources

  • Analysis of emission from mobile pollution Sources

  • Industrial gas analysis

  • Process measurement technology

  • Biogas research, etc.

  • Greenhouse gas monitoring

  • Process control

  • Building ventilation system management

  • Analysis of CO2 partial pressure and dissolved inorganic carbon

  • Atmospheric monitoring and meteorological research
