Overview
GB/T5450-1997 Bituminous Coal Aoa Swelling Meter Test
Product Details
Adopting advanced displacement sensors instead of traditional recording drums makes graphic drawing more accurate, simple, and worry free.
Automatically control the furnace temperature according to national standards, and display real-time control temperature values, heating speed, working time, and current opening
Automatically draw the curve of furnace temperature variation over time
Automatically draw curves of expansion displacement of two coal samples over time
Automatically diagnose common faults and instantly pop up a prompt window on the computer
And display various fault information and sound alarms
The temperature control and graphic drawing of the host are carried out by the computer according to the requirements of the national standard GB/T5450-1997.
Can run and control the experimental process online.
Automatically calculate the softening temperature (T1), starting expansion temperature (T2), curing temperature (T3), large shrinkage degree (a), and large expansion degree (b).
Print coal sample expansion curve and analysis report.
It can automatically save the relevant data of each experiment and can be queried at any time.

The AP-8 microcomputer Aoa expansion tester is a specialized instrument used to measure the expansion degree, an important indicator for characterizing the cohesiveness of bituminous coal. The experiment reflects the plasticity and cohesiveness of coal by testing its large shrinkage degree a and large expansion degree b.
