Performance characteristics:

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.
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.
It can automatically calculate the softening temperature (T1), starting expansion temperature (T2), solidification temperature (T3), shrinkage degree (a), expansion degree (b), print coal sample expansion curves and analysis reports.
It can automatically save the relevant data of each experiment and can be queried at any time.

Technical parameters:
Power: not exceeding 5kW
Temperature measurement range: 0-999 ℃
Accuracy: Level 0.5 Resolution: 1 ℃
Time measurement range: 0-999 minutes
Time measurement accuracy: ± 30s/24h Resolution: 0.1 min
Heating control: There are three preheating temperatures to choose from. After the formal test, the furnace temperature can be quickly restored to the temperature at the time of entering the furnace within 7 minutes, and then heated at a rate of 3 ℃/min. Has good temperature performance.
Power supply voltage: 220V ± 10% 50Hz
