Iekštelpu gaisa kvalitātes sensors

Fine particulate dust level: The laser air quality sensor can measure indoor dust levels in real time. 6-channel fine particulate quantity detection (particle count/liter)--PM0.3, PM0.5, PM1.0, PM2.5, PM5.0, PM10; 3-channel particulate quality detection (mcg/m³)--PM1.0, PM2.5, PM10 CO2 sensor and HCHO sensor: NDIR non-dispersive infrared carbon dioxide sensor with self-calibration, optical absorption chamber coating; electrochemical HCHO formaldehyde sensor with automatic calibration, dual platinum catalytic electrode, strong anti-interference ability. TVOC chemical pollution: Semiconductor TVOC VOCmeter can test various TVOC VOC volatile organic compounds such as benzene, toluene, xylene, aromatic hydrocarbons, aldehydes, hydrogen sulfide, etc., capturing changes in organic compound molecular concentration at thousandth-part levels. Supports data storage and export of 12 tests with date and time indication, frequency: once every 1 minute. Maximum memory capacity can be expanded to 8G, which can store up to 400 days of records Professional and original: air quality alarm base in accordance with US standard; 2200 mAh rechargeable lithium battery.
