Special equipment suitable for measuring the index of bituminous coal's gelatinous layer (maximum thickness Y of gelatinous layer, final shrinkage X, and three top indicators of volume curve). Complies with the requirements of GB/T479-2000 "Method for Determining the Index of Bituminous Coal Colloidal Layer".

The bidirectional communication between the computer and the controller enables comprehensive monitoring of the control equipment.

Automatically control and display the heating temperature of single or double furnaces.

Automatically measure and display the shrinkage of coal samples from single or double furnaces.

Automatically draw volume curves for single or double furnaces.

Automatically draw the curve of furnace temperature variation over time.

Automatically fill in the furnace temperature before and after every ten minutes.

At the inflection point of the volume curve, an alarm is triggered to remind the laboratory personnel to perform line operations such as starting, stopping, silencing, and running on the equipment.

Manually detect the data of the adhesive surface, input it into the computer through the keyboard for saving, automatically draw the upper and lower adhesive surface curves, and calculate the maximum thickness of the adhesive surface.

Automatically calculate test results and print out test records and reports.
Store previous test data for querying and printing.
