WEATHER RESISTING TESTER

PURPOSE:To facilitate the adjustment of temperature, to decrease the dispersion of the temperature of the surface of a sample and to make the test results constant by controlling the temperature of the sample from the upper and lower surfaces, and making an apparatus compact as a unitary body. CONSTITUTION:A filter 14 for cutting heat rays and ultraviolet rays at the lower surface, a lighting tool 11, a sample stage 15 which is arranged at the lower side of the lighting tool 11, a cooler 16 for controlling temperature and a moisture adding device 17 are all contained in the inside of a main body of one box-shaped tester. Wind whose temperature is controlled is blown on the upper and lower surfaces of the sample which is mounted on the sample stage 15. In this way, the wind having the constant temperature is sent on the upper and lower surfaces of the sample, and the test results become constant. The apparatus is constituted as the compact configuration as a unitary body. The accuracy in temperature control is excellent. Thus, the electric power is saved.
