Carbon Dioxide Detector Air Detector Indoor Temperature And Humidity Meter Visible Air Quality: Monitors carbon dioxide and formaldehyde concentration, temperature, and humidity in rooms and classrooms, offices, and other spaces. Compact size, small, lightweight and convenient, you can take it anywhere (Simultaneous measurement of 5 data) You can measure data at the same time between Co2, TVOC, HCHO, temperature and humidity. The digital display displays carbon dioxide (CO2) and formaldehyde concentration in color and numerical values at the same time display humidity and temperature in real time Built-in High Performance Sensor: Uses a NDIR sensor that absorbs infrared energy (wavelength) that is unique to the gas target, so it is highly selectable and achieves a high precision CO2 measurement. The CO2 hardness is always a significant fluctuation in conjunction with human movement. By measuring every second you can get a relatively stable measurement Real-time monitoring: The carbon dioxide detector detects indoor air stains, chemicals and colorless and odorless carbon dioxide that can harm the human body, and real-time update every second. The digital display colors and numbers allow you to check your current air quality level Wide range of uses: It can be widely used in a variety of situations, such as agricultural plants, greenhouse vegetables, production warehouses, material processing, interior (enclosed environment in homes, nursery rooms, rooms, cars, offices, etc.). You can install this air detector to check the air quality at any time and protect your family's health Specifications: Material: ABS & PVC Color: white Type: USB rechargeable Input: DC5V/1A Sensor: TVOC sensor Detection range: 0-5000PPM Resolution: 1PPM Display: LCD screen + backlight Battery: 3.7V/1200mAh lithium Temperature measurement range:-20~602 Humidity measurement range:5%~95%5 Measurement accuracy 50ppm 5% Packing List: 1 xCO2 Meter 1 xUser Manual
