XPD-06D Concrete Linear Expansion Coefficient Tester

XPD-06D is mainly used to determine the linear expansion coefficient of concrete according to DL-T5150-2001 standard. It can also be applied to materials such as asphalt, indoor formed specimens, and core samples drilled on site. Widely used in engineering quality inspection, teaching and research industries.
Main technical parameters
1. The automatic constant temperature water tank of the mixer can measure one specimen at a time, with the water level inside the tank about 50mm below the top of the specimen cylinder, and the temperature controlled within 0.5 ℃. The cooling rate can be controlled by a refrigeration unit.
2. Measurement: Differential resistance strain gauge, measuring 250mm.
3. A type of bridge used to test the strain value of resistance.
4. The thermometer has a measurement range of 0-100 ℃ and an accuracy of 0.1 ℃ display.
5. Test piece holder, with a diameter of 200mm and a height of 500mm, or using a covered white iron tube.
