About this item

• 【High Accuracy & Fast Refresh Data】Equipped with a high-performance chip that ensures fast and accurate datas. Utilizing advanced infrared (NDIR) sensor technology for the CO2, Electrochemistry sensor for the HCHO and TVOC. Compare with the common sensor, it is more sensitive, accurately and stable
• 【Two power supply options】 Our indoor air quality monitor is equipped with a built-in 1200mAh rechargeable lithium battery and a USB charging cable. It can last up to 8 hours on a single charge, making it suitable for portable use. If used for an extended period of time in a fixed location, it is recommended to insert the USB charging cable to ensure uninterrupted operation.

It can conveniently sit on a desk for easy visibility, making it an excellent tool for monitoring indoor air quality in our daily lives.
• 【Special note】In single-channel infrared detection technology, CO2 data will inevitably shift after transportation or use for a period of time, so manual calibration is required. If the CO2 data deviation is found to be large after the first startup, calibration is required. After the device is powered on, place it outdoors or near a window for more than 10 minutes. Press the multi-function button 3 times in succession and the calibration will be completed after a beep sound
• 【User-Friendly Operation】 Simply press and hold the "Power" button for 3 seconds to turn on or off the indoor Air Quality Detector. Once turned on, it will automatically begin detecting. The default temperature unit is Celsius (℃), but if you prefer Fahrenheit (℉), simply press and hold the "Power" button for 1 second to switch temperature units
• 【Multifunctional & Easy to Read】Since clean air means a lot to every one. Our indoor air quality monitor offers accurate monitoring of CO2, HCHO, TVOC, temperature and humidity, all displayed on utral-high definition color screen for people easy to identify and read. With its convenient design, you can monitor the environment at any time and it efficiently measures five crucial indexes for evaluating air quality.
