This indoor air quality monitor provides accurate results for many air quality measurements, including Carbon Dioxide(CO2), Formaldehyde(HCHO), Volatile Organic Compounds(TVOC), Temperature and Humidity. The temperature unit of the home air quality tester supports conversion between Celsius and Fahrenheit, and there is a MAX button for viewing the maximum data in the current test record.

Features:
➤ 1. 【Real-Time Monitoring and Smart Reminder】The air quality detector is responsive, the detected data is displayed on a screen, and then the system evaluates the risk level (GOOD or OK or POOR), and when the value exceeds the normal range, the buzzer sounds quickly. Mute button: Turn on or turn off the alarm sound. In silent mode, the mute symbol is not displayed and there is no alarm sound. The alarm sound is turned on by default.
➤ 2. 【1000mAh Rechargeable Battery and Low Battery Reminder】The carbon dioxide detector have a built-in 1000mAh rechargeable lithium battery, with a USB cable. When the battery is fully charged, the formaldehyde detector can last for 6-7 hours. When the battery power is too low, the battery frame will flash to remind the user to charge, while charging, the characters in the battery frame will flash in sequence until the battery symbol is fully displayed when the battery is fully charged.
➤ 3. 【High-Precision Sensor and Wide Range of Application】The indoor air quality monitor adopt an updated digital temperature and humidity sensor, and the high-precision sensor identifies and captures different pollutants in the mixed gas to ensure the accuracy of the measurement of various indicators. The air quality analyzer help monitor air quality and is widely used in the home, office, car, kitchen, bedroom, gym, hotel, camping, party and more.
➤ 4. 【LCD Display and Support Backlight】The handheld air quality tester is made of ABS material, and the excellent performance of high-temperature resistance and impact resistance makes the air pressure meter have a long service life. The large display screen supports LCD backlight to make the operation more convenient and the displayed data clearer and easier to read. Short press the backlight button to turn off or enable the backlight function.
