Automatic Concrete Shrinkage Expansion Instrument

Device name：Automatic Concrete Shrinkage Expansion Instrument 
Model：YC-SSJ 
Origin：Beijing
Purpose：To record automatically the shrinkage and expansion value of concrete specimens

Features:

1、 With independent intellectual：ZL201220557247.X，ZL201320664989.7,ZL 201220721026.1
2、 The 7-inch color touch screen can display and record the shrinkage and expansion value of the specimen and the ambient temperature and humidity in real time 
3、 The test data can be directly imported into the computer through the USB disk and processed by Excel 
4、 The YC-JS software is installed in the test host, and easy to be updated through USB 
5、 Unique programming ensures that the test data are continuous, and the test do not fail due to power failure 
6、 Three types can be chosen, YC-SSJ I and YC-SSJ II and YC-SSJ III for 1 group and 2 group and 3 group. 
7、 Dilatometer bench can be designed according to the user requirement.
