Product Details

5 in 1 Multifunctional Digital CO2 TVOC HCHO Air Quality Detector CO2 Meter

Model: BC126


  1. CO2-TVOC-HCHO over-standard alarm, low battery prompt, Type-c port charging
  2. Built-in lithium battery, non-dispersive infrared absorption principle sensor
  3. Usage scenarios: living room, bedroom, children’s room, study room, new car, school, hotel, etc…
  4. Eight functions: CO2 monitoring, TVOC monitoring, HCHO monitoring, temperature and humidity monitoring, intelligent alarm system, multiple anti-interference

Disturbance, air convection technology, greenhouse compensation calibration.

  1. Scientific design and accurate data: The heat dissipation effect of the product will affect its own monitoring performance. In terms of ventilation and heat dissipation, the scientific mesh design is adopted, and the heat dissipation is fast and accurate.
  2. Easily distinguish the air quality and make CO2/TVOC/THCH clear at a glance

Monitoring range:

a. Carbon dioxide (CO2): 350~2000 ppm

b. TVOC: 0.000-2.000mg/m³

c. Formaldehyde (HCHO): 0.000-1.000 mg/m³

d. Temperature: 0~90℃

e. Humidity: 0~99%RH


  1. High-performance chips (precise and more outstanding)

Accurately capture the weak current generated in the electrochemical reaction process, and accurately calculate the HCHO measurement results. Increase service life  Improve output efficiency  Effectively improve conversion  Newly implanted smart power saving


  1. Environmental protection and energy-saving, low battery reminder

Rechargeable, built-in battery, can last for 10 hours when fully charged 1200mA 10 hours 5V Battery capacity Standby time Charging voltage.
