Features:

* Semiconductor carbon dioxide sensors use electrochemical principles to convert carbon dioxide gas into electronic frequency using specific reactions. Sensor consists of the main reactor, electrolyte and electrode. When the carbon dioxide 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 carbon dioxide.

* 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 carbon dioxide monitor on and off. You can the n press the "Switch" button to change the temperature mode (°C to ° F).

* The role of carbon dioxide detector in daily life is mainly to detect the carbon dioxide content in the air and help people for advance the air quality. If the air quality is poor, people will take measures to improve the air quality and for ensure people's healthy life. So in school classrooms, offices, cars, hotels, kitchens, gyms, and other crowded places, carbon dioxide sensors can come in handy.

* This air quality monitor is designed for indoor spaces. Please close the doors and Windows before the exam. Otherwise, the data may be inaccurate. We recommend that you let it work for at least 60 minut es before reading the data.
