It is a kind of quality air quality detector, compact size, lightweight and portable. It adopts high-accuracy semiconductor TVOC sensors, real-time detection, automatic data refresh, with multiple applications. Large led display, you can clearly see the amount of electricity, CO2 value, TVOC value, HCHO value, temperature and humidity. Widely used: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, etc. Features: Compact size, lightweight and portable, easy to take out and carry with you. It uses high-accuracy semiconductor TVOC sensors, with stable working performance, can accurately detect the carbon dioxide value. It adopts electrochemical sensor module with stable detection performance, anti-interference ability, low consumption, and ensures long working time. Large led display, you can clearly see the amount of electricity, CO2 value, TVOC value, HCHO value, temperature and humidity.C And F switchable, real-time detection, automatic data refresh, reusable. It adopts air convection, which provides more accurate detection results. Equipped with the function of dividing the air quality level, three different colors correspond to different air quality levels, allowing you to know the current air conditions more accurately and graphically.400-1000ppm: green indicator light flashes, 1001-3000ppm: orange indicator light flashes, higher than 3000ppm: red indicator light flashes. The product does not need to be calibrated, can be tested after commissioning, and can accurately detect carbon dioxide. Hundreds of vents reserved on the housing not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide a delicate heat dissipation effect. Widely used: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, business offices, etc. Specifications:Name: air quality detectorMaterial: ABS Material: 1*built-in lithium battery, 5V, 1200mAh(Included)Display: LED display CO2 measurement ranges: 400ppm-5000ppmResolution: 1ppmAccuracy: (50ppm+5% reading)Temperature measurement ranges: -10.0C to 500C Resolution: 1Accuracy: 1Humidity Measurement Ranges: 10% RH-99% RHRresolvency: 1% RHomnification: 5% RH Working Temperature: 0-50C Operating Capacity: 20% RH-90% RHRuviable Measure: 160*90*41mm / 6.30*3.54*1, 61inProduct weight: 202g/7.13ouncePackage size: 190*120*60mm/7.48*4.72*2, 36inPackage weight: 406g/14.32ouncePacking list:1*air quality detector1*guidelineMany questions about Dropshipping services are as follows:1.
