Household 1.9inch 240*280 Resolution Color Display Air Quality Detector High Sensitive Semiconductor Sensors 5in1 HCHO TVOC CO2 Temperature Humidity Tester Type-C Interface This is a kind of quality air quality detector, compact size, lightweight and portable. Adopts high precise temperature and humidity sensors, real-time detection, automatic refresh data. Large LCD display, you can see the electricity quantity, CO2 value, TVOC value, HCHO value, temperature, and humidity clearly. Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, and etc.. Features: The compact body design, simple and fashionable appearance, you can put into your pocket and use wherever you want. 1.9inch clear definition color display, 240*280 resolution, the HCHO, TVOC, CO2, temperature and humidity are more intuitive and convenient to read. Equipped with high-precise semiconductor sensors, accurately identify and capture different pollutants in the gases, real-time HCHO, TVOC, CO2 gases concentration is more accurate. Adopts superior temperature and humidity sensors, with fine interference resistance ability, to ensures the accuracy of each indicator measurement, with stable working performance, and low power consumption. Built in high-sensitive intelligent chip for quickly air quality detection to ensure more accurate instrument detection. Equipped with air quality level division function, 4 different colors of font correspond to different air quality levels, allowing you to more accurately and more graphic know the current air conditions. Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the air and the machine, improve the air-flows passing rate to realize effective detection, but also provide greater heat dissipation effect. Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, etc. Specifications: Name: Air Quality Detector Material: ABS Color: black, white (optional) Battery: 1 * 700mAh built-in battery (included) Display: 1.9inch color display Working voltage: 3.7V Warm up time: 35s Data refresh rate: 2s Detection ranges: 0-9.999mg/m³ Operation humidity: 0-95%RH Working temperature: -10℃ to 50℃ Charging mode: Type-C interface Item size: 50.6 * 85 * 17mm / 1.99 * 3.35 * 0.67in Package size: 85 * 51 * 17mm / 3.35 * 2.01 * 0.67in Package weight: 120g / 4.23ounce Packing List: 1 * Air Quality Detector
