Luftpartikelzähler 8-in-1 PM1.0 PM2.5 PM10 CO2 TVOC HCHO Temperatur- und Feuchtigkeitsmesser Tragbares Luftqualitätsmessgerät Kohlendioxid

Eight-in-one air quality detector: this detector can simultaneously test and display the concentration, temperature, and humidity of PM1.0, PM2.5, PM10, CO2, TVOC, and HCHO. And it also has a Wi-Fi function.

Highly accurate sensor: It uses a highly accurate NDIR infrared carbon dioxide sensor, particle sensor, semiconductor sensor, optical sensor, and proximity sensor, with high sensitivity, strong anti-interference capability, stable operating performance, and low power consumption.

LCD color display: This air quality monitor has an LCD color display, which can automatically adjust the screen brightness to the ambient brightness, making the data clearly visible and preventing glare.

Easy calibration: Two calibration methods are designed; turn on the device and leave it for 5-10 minutes, press the multifunction button three times to perform manual calibration, and calibrate automatically after 24 hours after startup.

Parameter setting: Supports setting PM2.5 & CO2 alarm value, alarm sound, switching temperature unit, switching screen-off function, and setting screen-off time on the settings page.
