Portable air quality monitor adopts electrochemical sensor with stable performance and high detection accuracy, monitoring CO concentration, CO2 concentration, temperature and relative humidity in the air. Large-screen LCD digital display, real-time monitoring, perfect for home, office, school, warehouse, agricultural planting, etc.

Features:
4 in 1: Multifunctional air quality detector real-time monitors CO concentration, CO2 concentration, temperature and relative humidity in the air. Large digital screen with backlight, clear and easy to read, support alarm function.
High Accuracy: Using electrochemical sensor, plus high-performance chip, detection is more accurate, higher accuracy, and the accuracy can reach 1PPM.
Quick Heat Dissipation: With multiple ventilation holes, which accelerate the convection between the air and the detector, to achieve effective detection and provide a nice heat dissipation effect.
Built-in Battery: Equipped with 2400mAh high-capacity rechargeable battery, low power consumption and long endurance, no need to replace the battery frequently.
Wide Application: Lightweight and portable, it is suitable for home, office, school, warehouse, agricultural planting, etc. No need to calibrate at startup, automatic monitoring.
