MT29 detection of various parameters in addition to dust (PM) using infrared sensors, the rest of the semiconductor sensors, data is directed to a variable amount (detection of the approximate data range, can not accurately protect the data), the main cost-effective and multi-functional multi-parameter.

Product battery life: 5 - 7 hours. 5 hours: working with the screen always on; 7 hours: working in screen-off mode.

Features:

• The MT29 Air Quality Tester is an all-round environmental monitoring device that detects and displays 11 key indicators in real time, including CO2, CO, formaldehyde, TVOC, multiple particulate concentrations, temperature and humidity.

• It is equipped with a 2.8-inch TFT display, and through the Tuya Smart WiFi APP, users can remotely monitor data and view history.

• The product is compactly designed with alarm, timer and chronograph functions, and user-definable alarm thresholds.

• The built-in 2000mAh lithium battery is easy to charge. In addition, the device is self-calibrating to ensure accurate data.

• Whether it's a home, office or other indoor environment, this tester helps users understand air quality in real time to protect the health and safety of the living environment.

Package includes：

• 1 x Air Quality Detector.

• 1 x Type-C Data Cable.

• 1 x User Manual.

Note:

• If you find that the temperature is inaccurate after you get the device, don't worry: the temperature after some devices are turned on may cause some deviations due to the temperature test during production, so we also set the manual calibration temperature   :   Press the button 7 times, you can enter the manual calibration page of the temperature. After entering the page, click the button is "+", and double-click is "-". It is recommended not to calibrate during charging. The device has a temperature compensation plan during charging, which may be affected.
