Equipment usage and main functions：

The tester is a special instrument for measuring the expansion of coal,which is an important index to characterize the cohesiveness of coal.It meets the GB/T5450-2014 standard.

Features and performance:

✦The control system adopts advanced control technology,high temperrature control precision.

✦The software has temperature and displacement correction functions.Operating parameters,displacement curve of the expansion rod and temperature control curve can be displayed on the screen.

✦According to the displacement curve of expansion bar,softening temperature (T1),starting expansion temperature (T2) and curing temperature (T3) are automatically judged, maximum shrinkage (a) and maximum expansion (b) are automatically calculated.
