Abstract: A sweating simulator has a foundation panel (14), a panel (1) and a temperature control panel (2), a fixture for fixing a specimen, a container (7) for holding simulated sweat, a container (15) for collecting the simulated sweat, and a plurality of weighing scales for measuring masses of the simulated sweat supplied, evaporated and dripped from the specimen, respectively. The panel (1) and temperature control panel (2) constitute a simulated sweating plane for simulating wetting properties and temperature of skin. An upper middle position of the temperature control panel (2) has a sweating zone (3), which has a plurality of sweating pores (4). The temperature control panel (2) has a temperature sensor (8) and a heating element to control the temperature of the temperature control panel (2) around 33-35° C. to simulate the temperature of the human skin surface. The sweating rate of the sweating zone (3) is in the range of about 1 to 624 ml/h or about 0.004 to 2.
