Product Introduction

Working principle: Gas filtering related infrared absorption method

This instrument adopts gas filtering related infrared absorption method to ensure accurate and stable measurementCO₂The instrument is equipped with a broadband infrared light source behind the rotating gas filtration wheel, which has2One inflatable chamber, one chamber filled withCO₂Gas, it removes all componentsCO₂The absorbed infrared wavelength energy generates a reference beam, and another gas is filled with nitrogen gas, which allows the sample gas to pass throughCO₂The specific wavelength of absorption is measured, and during the measurement and reference period, the detector detects the difference in infrared energy, which is equal to the difference in infrared energy present in the detection chamberCO₂Proportionally, thus achieving the sample gasCO₂Measurement of concentration.
