CO2 sensor of water dissolved

CO2 sensor of water dissolved
ShenZhen ShenKaiAn Technology Co., LTD

SW205 Is a gas detection based on infrared absorption principle NDIR module, suitable for detection of co2 concentration in aqueous solution
SW205 Using patent design of optical cavity, imports of light source and dual channel detectors, realize the reference space in double light path compensation.
SW205 has good selectivity, no oxygen dependence, long service life
SW205 UART, IIC digital output and analog output voltage and frequency PWM output, convenient customer choice application;
SW205 offer clients zero calibration, calibration and sensitivity calibration clean air command, and to provide customers a manual calibration MCDL pin, convenient to customers in the use of the free flow of clean outdoor air relative zero calibration of sensor module
SW205 Using air convection diffusion and protective cover, both speed up gas convection diffusion velocity, and can breathe protective membrane. Detachable structure, easy to clean the sensor casing.
SW205 unique waterproof structure, removable, facilitate customer maintenance cleaning
SW205 Can be used to measure the water dissolved CO2 gas concentration size, can also be applied to the hvac refrigeration and indoor air quality monitoring, agriculture and animal husbandry production process monitoring and agricultural product storage condition monitoring, can be installed in the home network, ventilation system, controller, hanging use, robot, automotive applications, such as can also be applied to other device control air or oxygen monitoring quality
