1.1. Working principle
oxygen
The core component of MAP-200 is an electrochemical oxygen sensor. The principle of the sensor is similar to that of a battery. When gas passes through the sensor, the sensor can generate current corresponding to the gas concentration. The current value can be converted to the concentration value and displayed on the display screen. The sensor has excellent strength and stability, high repeatability and fast response speed. Even if the oxygen concentration is high, the sensor will not be saturated, so the application range of MAP-200 is very wide, the range is 0-99.9%, and the display accuracy is very high - in addition, the speed and accuracy are still excellent.
Carbon dioxide
CO2 sensor is a kind of independent non-dispersive infrared sensor, which is equipped with infrared light source and single wavelength filter. The sensor is a whole, without moving parts, and has a very strong structure. The range of CO2 sensor is 0-99.9%. Sensors are calibrated only once every six months, and readings are not affected by humidity or temperature.
