Features: Heat sealing tester is composed of the upper and lower heat-sealing sticks, of which the upper one is connected with a cylinder. There is an insulating plate in the upper part, which can prevent heat transmit to the cylinder. The heat-sealing stick is made of aluminum, and the center is heater. There is a silica gel plate in the upper part of the lower heat-sealing stick, which can mitigate pressure impact during heat sealing. Temperature measurement system was installed at the back of the heat-sealing stick.
