At the end of the test, it will automatically stop heating up, click the "Print" button to take out the test
report.
V 、 Notice
1. Heating is strictly prohibited when methyl silicone oil is not added to prevent dry burning from
damaging the heating tube
2. After each test is completed, be sure to take out the tested sample to prevent the next repetitive
heating to dissolve or decompose and increase the nail
The viscosity of the base silicone oil causes uneven heating.
3. The over-temperature protection should be adjusted to 250℃during the test (you can set it
according to your needs)
4. When the cooling water pipe is connected to the water, the pressure should not be too high, so that
the water pipe can be broken by explosion-proof, while saving water
5. During the high temperature test, a small amount of volatile smoke will appear (most obvious above
200℃), please do a good job of ventilation and smoke exhaust.
