<p>The apparatus for checking thermal behaviors of the precision instrument or electronic parts used in high-temperature, comprises a heating box (1) with a thermostat, for storing testpiece (T); a bridge box (2) having the strain detecting body, thermally isolated with the box (1); strain transmitting means for transmitting thermal behavior of testpiece in the box (1) to the strain detecting body at the box (2). The strain detecting body is the single/plural strain gauge (G) or the pressure-reduction element mounted at the strain transmitting shaft (3).</p> |
