Digital Thermo Hygrometer with Indoor Air Quality Monitor, Accuracy Calibration, Air Pollution Alert

Multifunctional & Industrial-Grade Accuracy - The Thermo hygrometer with advanced sensors can detect subtle changes in temperature, humidity, PM2.5, and CO2, and update their readings in real-time to reflect these changes. There is a 0.1°C (32°F) accuracy for temperature, and 0.001 mg accuracy for TVOC and HCHO. A pre-calibrated digital hygrometer measures temperature and humidity accurately.

Portable Test - It can monitor indoor air quality in your home, car, hotel room, greenhouse, and more. Portable power can be provided by a 1500mAh lithium battery when USB power is unavailable.

HD Touch Screen - By touching the screen, you can easily adjust the screen brightness and switch between interfaces. Observe power, temperature, humidity, and air quality data visually.

Air Pollution Alert - Once the surrounding environment has reached a serious pollution level, the detector will send out an alarm to prevent potential risks.

Historical Data Query - Connect to free APPS that allow you to query historical data on your mobile phone.

Certification - Passes RoHS, FCC, and CE compliance testing, and Noyafa is certified to the ISO 9001 standard.
