Data transmission can be completed through the host computer software;Acrylic clear case shell, high transmittance to be looked through;Built in for ARM 32 bit processor, accurate detection & system fluency2.8inch TFT screen, colorization display, wide angle vision up to 180 degree;High sensitivity sensor ensures the high accuracy in data collections;Semi-closing design performs excellent in heat radiation, long-life useMultipurpose in quality detection in PM1.0, PM2.5, PM10.0, , temperature&humidity, suspended particulate matter;Real-time detection results will be shown on screen in corresponding colors related to collected datasLightweight, easy to use and be a straightaway in data interpretation; supply in DC 5V universal, usb socket, car charger, bank, etc;Suitable for home/office and car or part scope on quality detectionFont color: Multi ColorsResolution Ratio: 320x240Operation Current: 1-2ATemperature Measure Range: -20 to 60 CelsiusAccuracy: +/- 0.1 CelsiusLanguage Version: EnglishWorking Principle:Multi-angle Scattering Detection, irradiation in the suspended particulate matter in the and generate scattering. Scattered light will be collected in a specified angle at the same time. According to the scattering intensity, time-varying curves can be obtained through the sensor. Being processed by the microcomputer processor, equivalent particle diameters and the number of suspended particulate matter with different sizes in per unit volume can be obtained.colour: transparentMaterial: acrylicsize: Approx. 8.5x6.5x3.7cm/ 3.35x2.56x1.46inchPackage Contents: 1 x PM2.5 Quality Detector1 x USB CableOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
