The XPD-06D instrument meets the requirements of the "Test Code for Hydraulic Concrete DLT5150-2001", "Test Code for Hydraulic Concrete SL 3562-2006", and "Test Code for Hydraulic Asphalt Concrete DL-T536-2006". It is mainly used to determine the linear expansion coefficient of concrete, and 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.

Concrete linear expansion meterMain 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. Digital bridge, used to test the amount of resistance strain.

4. The thermometer has a measurement range of 0-100 ℃ and an accuracy of 0.1 ℃ display.

5. Test specimen rack, diameter 200mm, height 500mm or using covered white iron tube.

6. Test accuracy: 1um.

7. The equipment adopts fully automatic touch screen control, which has the advantages of easy operation, stable testing performance, and high testing accuracy.

Concrete linear expansion meterInstrument configuration:

1. One test host (constant temperature box)

2. One long rod thermometer (0-100 ℃)

3. One digital bridge (including operating instructions)

4. One differential strain gauge

5. One sample rack
