Air Quality Monitor CO2 Detector USB Charging Carbon Dioxide HCHO Temperature Humidity Detector with Large Screen

Feature: 1. Infrared Models: The carbon dioxide detector adopts infrared probe, which has good accuracy, stable performance, strong anti interference ability, low consumption and long service life. 2. Large Screen Display: The CO2 detector has a large screen that can display power, CO2, temperature and humidity, making it convenient for you to check the air quality at any time. 3. Different Font Colors: Equipped with a large screen, different font colors show different air quality. 400‑800ppm, green is normal. 800‑1800ppm, yellow concentration is slightly highe. More than 1800ppm, red concentration is super high. 4. Rear Vent Function: The rear vents not only accelerate the convection between the air and the machine for effective detection, but also provide good heat dissipation. 5. Wide Range of Applications: Air quality monitor CO2 detector is suitable for a wide range of places, can be used in schools, hospitals, restaurants, shopping malls, offices, etc. Specification: Item Type: Air Quality Detector Product Material: ABS, Electronic Components Weight: Approx. 369g 13.1oz Product Size: Approx. 16x9.2cm 6.3x3.6in Carbon Dioxide Detection Range: 400 5000ppm Carbon Dioxide Detection Accuracy: 1ppm HCHO Detection Range: 0.005 2mg M3 TVOC Detection Range: 0.008 2mg M3 Temperature Measurement Range: 1 70 celsius Temperature Measurement Accuracy: 1 celsius Humidity Measurement Range: 0percent 99percent RH Humidity Measurement Accuracy: + 2percent Battery: Built in Rechargeable Lithium Battery, Model 18650, Capacity 1200mAh (Delivered with Built in Battery).
