<p>PURPOSE:To enable a melted carbon dioxide gas concentration within a bath water to be measured accurately in a simple configuration by providing an air supply portion at a middle of a ductwork that takes in water where carbon dioxide gas is dissolved, providing an atomizing portion at the tip, and then providing a measuring device with a concentration of carbon dioxide gas which turned into gas. CONSTITUTION:In a carbon dioxide gas concentration measuring system, an air supply portion 7a is provided halfway at a ductwork 1 for taking in water where carbon dioxide gas is dissolved and an atomization portion 3 is provided at the tip and a measuring device 9 of carbon dioxide gas which became gas due to atomization is provided. When a pump 2 is driven, water within a bath 10 is sucked from a water- suction portion 5 and is atomized from a tip portion 1bb to the atomization portion 3. In this case, air is introduced from an air supply pipe 7 and is led into the atomization portion 3 and then the gas supply portion 7a results in a negative pressure and further air is sucked. Carbon dioxide gas which is dissolved in water is evaporated, is separated from the bath water within an gas/liquid separation portion 4, and is exhausted from an exhaust pipe 8. Then, the concentration is measured by a measuring device 9 which is an infrared rays sensor, thus obtaining carbon dioxide gas which is dissolved in the bath water.</p> |
