Feature
●[Technical principle] Semiconductor CO2 sensors use electrochemical principles to convert CO2 gas into electronic frequency using specific chemical reactions. Sensor consists of the main reactor, electrolyte and electrode. When the CO2 gas passes through the reactor into the sensor, a reduction reaction occurs at the electrode, generating a current. By measuring the size of the current, can determine the concentration of CO2.
●[Easy to Carry&Use] compact size body, hollow design, easy to carry and ventilation. Press and hold the "On" button on the right for 3 seconds to turn the CO2 monitor on and off. You can then press the "Switch" button to change the temperature mode (°C to ° F).
●[Universality]The role of CO2 detector in daily life is mainly to detect the CO2 content in the air and help people advance the air quality. If the air quality is poor, people will take measures to improve the air quality and ensure peoples healthy life. So in school classrooms, offices, cars, hotels, kitchens, gyms, and other crowded places, CO2 sensors can come in handy.

Description
---Semiconductor Principles---
Semiconductor CO2 sensors adopt electrochemical principles
Semiconductor model built-in TVOC sensor, is to determine the CO2 content by measuring the organic gas content in the air.
The organic gas content and the CO2 content are remaining in a stable ratio range, so we can deduce the CO2 content by measuring the organic gas content.
