Goodhd Infrared CO2 Detector Temperature And Humidity Detector Air Quality Detector

Features: - Brand new and high quality. - Made of high quality materials durable and practical. - Infrared version of carbon dioxide detector: The infrared carbon dioxide gas sensor utilizes the absorption of characteristic infrared wavelengths by carbon dioxide gas in accordance with the Lambert-Beer law. The basic principle is that the infrared light source emits an infrared beam through the sampling chamber and uses the carbon dioxide gas component to absorb infrared rays of a specific frequency. - Comparison with electrochemistry catalytic combustion solid electrolyte semiconductor photoacoustic method NDIR - The detection method has the following advantages: good selectivity not easy to be affected by harmful gases and poisoning and aging fast response speed and good stability high signal-to-noise ratio and accurate detection. Specification: - Measuring range: 10m² - Measurement object: air - Measurement accuracy: ±2% - Resolution: 320*320 - Voltage: 3.7(v) - Size: 86*50.6*17mm (mm) - Power supply: direct charge - Specification: white black (optional) Package Included: 1*Air quality detector (optional) Notes: 1.
