Indoor CO2 Monitor LFG203

LEFOO LFG203 indoor carbon dioxide transmitter is based on the different gases have different absorption capabilities for infrared light in a specific band, and measures the concentration of the measured gas by measuring the degree of infrared light absorption. Compared with electrochemical sensors, it has the characteristics of long life and good stability. The imported high-performance NDIR sensor is used for CO2 concentration measurement, with rapid response, stable performance, high accuracy, wide power supply range, small size and simple installation, which is an ideal choice for indoor carbon dioxide measurement. It can be widely used for CO2 concentration measurement in home space, office space, factory car library warehouse and other environments.



Features

* Imported high-performance NDIR sensor

* Lightweight and beautiful shell design, using LCD backlight display

* Good long-term stability and reliability, with ABC self-calibration

* A variety of output methods are optional, standard 86 box installation method
