An observation window (2) is fixedly mounted on one side of the housing (1), a detection port (3) is formed at the middle portion of the observation window (2), and a mounting block (4) is fixedly mounted on the side of the observation window (2) close to the detection port (3). The tester is provided with aluminum plates (12). When the tester operates, high temperature is generated inside. At this time, the aluminum plates (12) perform cooling by means of a cooling fin (14), and then cold air is delivered to the inside of the housing (1) by means of fan blades (21) to carry out cooling. A heat sink (16) is mounted on the outside of the cooling fin (14). The cooling fin (14) transfers heat to the heat sink (16), and water inside the heat sink (16) takes away the heat. When the cooling is performed, a fan (13) and a water pump (17) are turned on via a switch (25), a pumping port (26) on the top of the water pump (17) pumps internal hot water away from a drain port (23), external room-temperature water is introduced to a water inlet (22), and the hot water is discharged from a water outlet (27) by means of the operation of the water pump (17). In this way, a circulation is produced between the water inlet (22) and the drain port (23), achieving a cooling effect.
