HNAP-4 microcomputer Aoya expansion tester

Features of the microcomputer Aoya expansion tester:

The Aoya expansion test is an experiment that reflects the plasticity and cohesiveness of coal by testing its shrinkage degree a and expansion degree b.

Replacing traditional recording drums with displacement sensors makes graphic drawing more accurate, simple, and worry free.

Automatically control the furnace temperature according to standard requirements, and display the control temperature value, heating rate, working time, and current opening in real time

Automatically draw the curve of furnace temperature variation over time

Automatically draw curves of expansion displacement of two coal samples over time

It can automatically calculate the softening temperature (T1), starting expansion temperature (T2), curing temperature (T3), shrinkage degree (a), and expansion degree (b).

Automatically save relevant data for each experiment, which can be queried and printed at any time, including coal sample expansion curves and analysis reports

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 standard GB/T5450-1997.
Real time display of coal sample expansion curve.

Real time display and control of temperature value, heating rate, working time, and current opening.

Can run and control the experimental process online.

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.

Technical parameters of the microcomputer Aoya expansion tester:

Power: not exceeding 5kW Temperature range: 0-999 ℃
