Abstract
A measuring apparatus includes a base and a testing module. The testing module is received in the base and includes a temperature-controlling bucket, a testing cylinder, and upper and lower pistons. The temperature-controlling bucket extends in a vertical direction and has a bucket wall having a bucket inner surface and a bucket outer surface opposite to the bucket inner surface. The testing cylinder extends in the vertical direction, is received in the temperature-controlling bucket, and has a cylinder wall having a cylinder inner surface and a cylinder outer surface opposite to the cylinder inner surface. The upper and lower pistons plug top and bottom ends of the testing cylinder, respectively. The upper piston has a receiving room located inside the upper piston, and has a piston temperature sensor and a piston heating wire received in the receiving room.
