3 In 1 CO2 PM2.5/10 NH3 Sensor Ammonia Detector Tester, Wall-Mounted Humidity and Temperature Sensor
QCO2 carbon dioxide sensor uses the principle of non-dispersive infrared (NDIR) to detect the concentration of CO2 in the air. It adopts advanced infrared absorption gas detection technology, with precise optical path and well-designed circuit. Built-in temperature compensation circuit to ensure measurement accuracy. No oxygen dependence, long service life. QPM dust sensor uses the principle of laser scattering to detect the concentration of dust particles in the air. The minimum detectable particle size is 1.0μm. The sensor has good consistency and stability. Depending on the use environment, you can choose indoor or outdoor models. QNTH ammonia temperature and humidity sensor uses electrochemical detection probe and industrial-grade control chip, with high measurement accuracy, good stability and strong anti-interference ability. It is widely used in air quality monitoring, greenhouses, smart homes, schools, hospitals, warehouses, industrial production and other fields and places where ammonia concentration needs to be detected.
Why choose the 3 IN 1 sensor?
- Electrochemical sensor design. Detect ammonia gas in high sensitivity, fast response time, and low maintenance requirements.
- Adjustable ammonia gas alarms. Supports Carbon dioxide-PM2.5/10-ammonia NH3 gas alarms limit setting. Monitoring indoor ammonia concentration intelligently.
- Wall-mounted design. Not only can place it on the desk, but also can hang it on the wall. backlit LCD screen, display the ammonia gas value clearly.
