**PENCHEN 3-in-1 CO2 Temperature & Humidity Monitor - Digital Air Quality Detector for Home, Indoor Pollution Tester with LCD Backlit Display - Ideal for Bedroom, Office, and Nursery**

Product Description

Features: Uses high accuracy semiconductor sensors, with stable working performance, can accurately detect carbon dioxide value. Adopts air convection design, which can provides more accurate detection results, and the detection ranges from 400ppm to 5000ppm. Large LCD display, 3in1 design, you can see the carbon dioxide concentration, real time temperature and humidity data clearly. 4-color color-circle design, different font colors display different air quality, green 0-799ppm, light green 800-1199ppm, orange 1200-1599ppm, red 1600-1999ppm, 2000ppm above four colors flash at the same time. Strong anti-interference ability, low consumption and long service life. The product does not need calibration, it can be tested after booting, and it can accurately detect carbon dioxide. Hundreds of ventilation holes reserved on the housing not only accelerate the convection between the air and the machine, thereby realizing effective detection, but also provide a fine heat dissipation effect. Widely applications: agricultural planting, greenhouse vegetables, production warehouse, material processing, home interior, etc..
