Overview
Infrared thermopile gas sensors can measure the concentration of carbon dioxide gas components by the change in the resistance of the thermistor element in it. The product is packaged by TO-46 metal tube shell, the window is equipped with a narrow bandpass filter selected for carbon dioxide gas, and the infrared filter, thermistor and other electronic components are integrated inside, which has the advantages of high reliability and high sensitivity.
Feature
★ To-46 housing
★ High sensitivity
★ NTC Thermistor Compensation
★ Fast response
★ 4.26μm narrow bandpass filter
