Specifications: Display mode: LCD Formaldehyde detection range: 0.000~1.999 mg/m TVOC detection range: 0.000~9.999 mg/m TVOC Effectors: Benzene, Hydrocarbons, Alkanes, Olefins, Ketones, etc. Detection Range PM1.0/PM2.5/PM10: 0~999 g/m Temperature measurement range: 0~50 Humidity measurement range: 20~90% RH Battery: 1200mAh lithium battery Charging time: about 4 hours Duration: approx. 2 hours USB interface: Type C interface Input: 5V/1A Working Environment: 5~40,<90%RH Storage Environment: 0~50,<90%RH Size: 151,69,45mm Characteristics: *Color display screen intelligent air detector, accurate independent multi-core sensing+APP intelligent control. Innovate closed detection, APP monitoring and find the source of pollution. Put the detector in the closet, bed, car and other objects and close the door. Real-time monitor the pollution value through APP to find the real pollution source. *12 functions, 24-hour real-time monitoring, opening the era of air detection microcomputer. -Accurate determination of formaldehyde -PM 2.5 air quality test -Air quality test PM10 -Air Quality Check PM1.0 -Accurate detection of TVOC and dumb -Smart aldehyde and haze removal calculator -Air convection system -Temperature detection in real time -Real-time moisture detection -Analysis of the air quality curve -24-hour air detection -Memory calibration *Long term recording and tracking of formaldehyde/TVOC concentration trend. The data can be viewed through APP at any time since the use of the instrument, and the indoor data can be compared and analyzed for a period of time to avoid the impact of accidental interference on the test results, and the overall concentration trend can be visualized for real-time tracking and solution formulation become. *The electrochemical sensor can effectively eliminate the interference of other gases through multi-layer filtration; Accurately detect formaldehyde molecules. *The electrochemical sensor uses the primary cell reaction principle of formaldehyde, and its output signal is highly linear with the concentration of formaldehyde. With the cooperation of multi-layer filter technology, it can detect formaldehyde molecules more accurately, and has stronger interference ability to non-formaldehyde molecules, and can achieve more accurate measurement.
