IIAutomatic layout and dual control non flammability test furnace for building materialsProduct functional features
1. Dual control mode: can be controlled on the touch screen or on the computer, and the operation mode can be easily switched; One device can be operated by multiple computers simultaneously, multiple computers can be online at the same time, and LAN sharing can be achieved; (Users should bring their own computers and printers; we will send out the upper computer software, router, and network cable along with the equipment)
2. Equipped with automatic layout function, the sample can be automatically placed into the furnace after the temperature stabilizes. The sample basket will automatically rotate 90 degrees after being discharged from the furnace, and when changing the sample. The automatic layout process can be stopped at any time, and the sample basket can automatically return to its initial position;
3. Adopting microcomputer technology and thyristor technology, the temperature of the furnace body is adjusted through power regulation
2. High degree of automation, displaying and recording the temperature inside the furnace, at the center of the sample, and on the surface of the sample during testing, and automatically displaying operation prompts for the testing steps
3. Historical curves can be queried to automatically determine temperature balance
4. The testing process is safe, reliable, and easy to operate
5. Customized mold forming refractory furnace with good insulation performance
6. Using high-quality strip heaters, the furnace temperature can be raised to 900 ℃
7. PLC+NAbview software can display real-time furnace temperature, sample center temperature, and sample surface temperature curves, enabling automatic control, data acquisition and processing, data storage, and output of measurement results.
8. The top is equipped with an observation mirror, which facilitates users to safely observe the combustion status of the samples inside the furnace.
