User-Friendly Display: </strong>Equipped with a TFT color display, the air quality monitor allows you to see all test data at a glance. Its intuitive interface and curve function make tracking air quality changes simple and efficient.<br /> <br /><br/><br/><span><strong>Specification:</strong></span><br /> <span>Origin: Mainland China</span><br /> <span>Description: It uses a semiconductor TVOC sensor, which is cheap and highly sensitive. The disadvantage is that it can only detect, and compared with infrared sensors, the data is not accurate enough (called qualitative but not quantitative), and can only detect mixed carbon dioxide, such as carbon dioxide exhaled by the human body, but cannot detect pure carbon dioxide.<br /> Key functions:<br /> Single click on the main interface to switch the temperature, double click to turn off and on the sound, 3 clicks to enter the calibration interface (the calibration interface does not support operations unless the device is turned off), 4 clicks to enter the screen off (click to turn on the screen in the screen off state), 5 clicks to enter the curve and formaldehyde interface (click on the curve interface to switch PM2.5, formaldehyde, TVOC Formaldehyde comparison interface, (double-click on the formaldehyde comparison interface to record the previous set of data, double-click again to record the next set of data) 6 clicks to enter the time setting interface, 3 clicks on the time setting interface to select change, single click to add 1, double click to subtract 1, 5 clicks to exit after setting, or wait for 5 seconds to automatically return to the main interface. 7 clicks to enter the temperature adjustment interface (single click to add 1 degree, double click to subtract 1 degree, 5 clicks to exit or exit the interface without operation for five seconds)<br /> Parameters:<br /> Display color: The parameter is displayed in green, and the color will change if it exceeds the warning value<br /> Curve meaning: Displays historical 24-hour data<br /> Built-in lithium battery: 1200mAh<br /> Rated voltage: 3.7V<br /> Charging time: 2-3 hours<br /> Usable time: 240-360 minutes<br /> Shell material: ABS<br /> Product size: about 90.00x70.00x35.00mm<br /> Product size: 3.54x2.76x1.38inch<br /> </span><span></span><br /> <br /> <p> <strong>Note:</strong><br /> Due to different monitor settings and lighting conditions, the actual color of the item may vary slightly from the pictures.
