IN-SITU PROBE APPARATUS HAVING INFRARED CARBON DIOXIDE DETECTOR AND COOLING UNIT FOR MEASURING CARBON DIOXIDE

摘要

PURPOSE: An in-situ probe measuring device with a cooling unit and an infrared carbon dioxide detecting device is provided to decrease the temperature of the measured target gas by making the temperature proper to measure the gas using a carbon dioxide detecting device, thereby improving the accuracy of the measurement and extending the lifetime of the carbon dioxide detecting device. CONSTITUTION: An in-situ probe measuring device comprises a probe(10), a cooling unit(20), a carbon dioxide detecting device(30), and a control unit(40). The probe is inserted into a duct, thereby being installed. The cooling unit is installed in and end portion of the probe and outside of the duct. The carbon dioxide detecting device is installed in a rear end of the cooling unit. The control unit is electrically connected to the carbon dioxide detecting device and measures the concentration of the carbon dioxide extracted by the carbon dioxide detecting device.
