CO2 monitoring for water - Water Quality Sensors
1, Introduction
KWS-5000 can be used to measure the concentration of dissolved CO2 gas in water. It can also be used for HVAC and indoor air quality monitoring, agricultural and animal husbandry production process monitoring, agricultural product storage status monitoring, and can be installed in home networks, ventilation systems and controllers, wall-mounted, robotic and automotive applications. It can also be applied to other equipment to control air quality or hypoxia monitoring.
KWS-5000 is a gas detection module for detecting the concentration of carbon dioxide in aqueous solution. It adopts patented optical cavity, imported light source and dual-channel detector to realize spatial dual reference compensation.
