KWS5000 Water Dissolved CO2 Sensor - Carbon Dioxide in Water

KWS- 5000 Disolved CO2 Sensor in Water – Carbon Dioxide in Water 


Kacise KWS-5000 is a gas detection module based on NDIR infrared absorption principle, which is suitable for detecting the concentration of carbon dioxide in water solution. KWS-5000 adopts a patented optical cavity, adopts convection diffusion ventilation method and protective cover, which not only accelerates the gas convection diffusion speed, but also waterproof and breathable. Unique waterproof structure, detachable, easy to clean the outer casing of the sensor.


  • Unique waterproof structure, can be disassembled
  • Lightweight housing for easy field installation
  • Rich interface, convenient for customers to choose
  • Provides zero calibration, sensitivity calibration and clean air calibration

Carbon dioxide in  water application

  • Aquaculture
  • Agricultural greenhouse environmental monitoring
  • Biopharmaceutical Environmental Monitoring
  • Water Quality Analysis
  • Solution analysis
