New-3 In 1 CO2 Meter Air Quality Monitor Handheld 5000Ppm CO2 Monitor Measurement Carbon Dioxide / Detector _x000D_ New-3 In 1 CO2 Meter Air Quality Monitor Handheld 5000Ppm CO2 Monitor Measurement Carbon Dioxide / Detector _x000D_ _x000D_ _x000D_ Summary: S8606 / S8601A CO2 detector adopts carbon dioxide sensor and temperature and humidity sensor. The instrument is used to measure carbon dioxide content and temperature and humidity in the environment, and is widely used in agriculture, aquaculture and industrial fields. Such as: planting greenhouses, livestock farms, beer, carbonated beverages, energy saving and environmental protection products production process and underground operation safety production. In our daily living environment such as: kindergartens, schools, office buildings, shopping malls, supermarkets, stations, hospitals and other public places, monitoring of carbon dioxide concentrationcan improve the quality of air, therebyimproving learning and work efficiency; Prevent the spread of infectious diseases and ensure public health and safety. Features: Measuring CO2 content, temperature, humidity Temperature unit: C / F conversion Measurement result HOLD function LCD two-line display, showing both CO2 content and temperature and humidity. Green/yellow/red backlight prompt function Automatic shutdown function Description: 3 x 1.5V AAA batteries (does not include) Warmtips: The measuring range of the instrument is 400-5000ppm. If it exceeds 5000ppm, H1 will be displayed and there will be a continuous beep. It needs to be shut down and restarted before testing. S8601 is a semiconductor sensor / S8601A is an infrared sensor.
