PURPOSE:To maintain a normal low temperature test environment by storing a non-conductive antifreeze liquid into a low temperature tank. CONSTITUTION:A non-conductive antifreeze liquid 2 never solidifying even under a very low temperature is stored into a low temperature tank 1 and cooled down to a very low temperature with a freezer 3 arranged in parallel therewith. An IC13 to be tested is carried in plurality as inserted into a terminal board 12 and with the door 4 of the low temperature tank 1 left open, the board 12 is inserted into a socket 11 of a connector 9 to connect the IC13 electrically to a specified tester. But as the connector 9 is submerged into the antifreeze liquid 2, there is no dew formation in the socket 11 or the like. Thus, a normal testable condition can be maintained.
