Product Details
KWS-5000 Dissolved CO2 Sensor In Water
Introduction
KWS-5000 is a gas detection module based on NDIR infrared
absorption principle, which is suitable for detecting the
concentration of carbon dioxide in aqueous 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.
