Suitable for testing the burning performance classification of Class A fireproof materials in the burning performance classification of building materials GB8624

Second, product features
1. Adopt microcomputer technology and thyristor technology to adjust furnace temperature through power
2. The operation can be controlled on the touch screen, the degree of automation is high, and the temperature inside the furnace, the sample center and the sample surface are displayed and recorded during the test, and the test step will automatically jump out of the operation prompt.
3. Query historical curve to automatically judge temperature balance
4. The test process is safe and reliable, and easy to operate.
5. Customized version of mold forming refractory furnace, good thermal insulation performance
6. Using a high quality strip heater, the furnace temperature can be raised to 900 °C
7. PLC+NAbview professional software displays the furnace temperature, sample center temperature and sample surface temperature curve in real time, which can realize automatic control, data acquisition and processing, data storage and output measurement results.
8. The top is equipped with a sight glass to allow the user to safely observe the burning state of the sample in the furnace.

Tips: The non-combustible test furnace body has two kinds of round and square, and the default is shipped according to the shop!
