3 in 1 Air Quality Monitor 400-5000PPM Carbon Dioxide Detector CO2 Meter Alarm

Description: Product Description: [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 the n 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 people's healthy life. So in school classrooms, offices, cars, hotels, kitchens, gyms, and other crowded places, CO2 sensors can come in handy. [Note] 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.
