LR-JCB-3 Automatic Building Material Non-combustibility Test Furnace

Product features

Dual control mode: the operation can be controlled on the touch screen or the computer, and the operation mode can be switched arbitrarily;A device can operate several computers at the same time, several computers can be online at the same time, LAN sharing can be achieved;
With automatic lofting function, the sample can be put into the furnace automatically after the temperature is stable, and the sample basket can be rotated 90 degrees automatically after the outlet of the furnace, when the sample is changed.Automatic lofting process can be stopped at any time, the sample basket can be returned to the initial position automatically;
Adopt microcomputer technology and silicon controlled technology to adjust the temperature of furnace body through power
4. High degree of automation, display and record the temperature of furnace, sample center and sample surface during the test, and the operation prompt will pop up automatically for the test step
5. It can query the historical curve and automatically judge the temperature balance
6. The test process is safe, reliable and easy to operate
7. The customized mold is used to form the refractory furnace with good heat insulation performance
8. Use high quality strip heaters, furnace temperature may rise to 900 ℃
9. PLC+NAbview professional software can display the temperature inside the furnace, sample center temperature and sample surface temperature curve in real time, which can realize automatic control, data collection and processing, data storage and output measurement results.
10. Observation mirror is equipped on the top to facilitate users to safely observe the burning state of samples in the furnace.
