Multi in one air quality monitoring transmitter
1. product description
RK-210 is an air environment comprehensive index monitor independently developed by our company. It is used to detect PM2.5, PM10, temperature, humidity, pressure, light, ultraviolet light, TVOC, O2, carbon dioxide (CO2) and carbon monoxide in the air environment. (CO), formaldehyde (CH2O) micro pressure difference and other parameters. The function is very powerful, basically covering various indicators reflecting air quality.The transmitter adopts imported original sensor and calculation chip, with high precision, high resolution and good stability. It is widely used in building HVAC, building energy saving, smart home, schools, hospitals, airport stations and other places.2. Functions and features
