At the same time, the bevel gear motor 33 and the gas-liquid mixing pump 44 can be cooled. When passing through the temperature conducting block 52, the temperature conducting block 52 transfers the temperature of the newly inhaled liquid to the tested liquid, thereby achieving the effect of cooling the liquid to be tested and heating the tested liquid at the same time. Then the tested liquid flows into the hose 2 55 and flows out from the outflow head 56 into the original liquid.
