INKBIRD Air Quality CO2 Monitor AK3 Indoor CO2 Meter Accurate Tester for Formaldehyde(HCHO) TVOC Temperature and Relative Humidity Real-Time Gas Detector 350~2000ppm Range

Highlights

• 【Real-Time Measurement】The air quality monitor can accurately detect the level of Carbon Dioxide(CO2), Volatile Organic Compound(TVOC), Formaldehyde(HCHO), temperature and humidity, and updates the measured results per second on the colorful display.
• 【Accurate Results】Adopted a high-precision infrared sensor and a built-in high-performance chip, which can accurately capture the weak current generated during the electrochemical reaction, to calculate the carbon dioxide measurement result.
• 【Smart Alarm】Air quality can be divided into three levels: GOOD, OK, and POOR.
• When the measured air level turns OK, the indicator will turn YELLOW and the device will sound “Bee--Bee” twice to remind you.
• When the measured air level turns into POOR, the indicator will turn RED and the device will sound “Bee--Bee--Bee” twice, you will see the color clearly on the large screen.
• 【1200mAh Built-in Lithium Battery】Takes 2.5 hours to charge the battery, lasts 6 to 8 hours when it is fully charged and can be connected to power during use.
• 【Wide Application】The device is ideal for monitoring air quality in cafeterias, restaurants, schools, offices, greenhouses, factories, hotels, hospitals, etc.
• 【Note!】Air changes constantly, and the measured results will be affected at the same time, please focus on long-time measurements(over 60 minutes) to get a conclusion about the air quality of the overall environment.
