Performance characteristics

The host adopts a high-precision rotary encoder structure, which increases the sampling frequency and accuracy, and meets the displacement accuracy requirements of the new standard.

The furnace is made of copper with high thermal conductivity efficiency, and the outer diameter is thickened on the basis of the old model to improve the uniformity of the material barrel; The upper and lower partitions are made of polymer insulation materials, which enhance the overall insulation performance and are not too hot to touch;

Specially designed pressure rods, cleaning rods, die plugs, and die cleaning rods are convenient and highly practical.

The temperature controller adopts the Japanese Omron brand, with high accuracy and good stability.

The touch screen operation interface is clearer and more intuitive, and the operation is simple and easy to understand.

Equipped with a microcomputer controller specifically developed for melt finger testing machines; The entire process control, data processing, and data printing of the experimental process can be carried out, and the test results can be printed out through the equipped micro printer.

Equipped with an aluminum alloy weight box.
