Product Description

TPAP-4 Microcomputer Oya Expansion Tester

Features:
Oya Expansion Test is an experiment to reflect the plasticity and cohesiveness of coal by testing the maximum shrinkage a and the maximum expansion b of the coal.

The advanced displacement sensor is used to replace the traditional recording drum, which makes the graphic drawing more accurate, simple and worry-free.
The furnace temperature is automatically controlled according to the requirements of the national standard, and the control temperature value, heating speed, working time, and current opening are displayed in real time.
Automatically draw the curve of furnace temperature over time
Automatically draw the curve of the expansion displacement of two coal samples as a function of time
Automatic calculation of softening temperature (T1) and start of expansion temperature (T2)
Curing temperature (T3) maximum shrinkage (a) and maximum expansion (b)
The relevant data of each test is automatically saved and can be queried at any time.
Print coal sample expansion curve and analysis report
Automatically diagnose common faults, and pop up prompt windows on the computer immediately
And display various fault information and sound alarm
According to the requirements of GB/T5450-1997, the computer controls the temperature of the host and draws graphics. It also can meet ASTM D5515
Real-time display of coal sample expansion curve.
Real-time display control temperature value, heating rate, working time and current opening.
It can run and control the experimental process online.
It can automatically calculate the softening temperature (T1), the starting expansion temperature (T2), the curing temperature (T3), the maximum shrinkage (a), and the maximum expansion (b).
Print coal sample expansion curve and analysis report.
It can automatically save the relevant data of each test, which can be inquired at any time.
