There are three elements in heat sealing of plastic films -- temperature, pressure and dwell time. Usually, we need to find a proper seal temperature, pressure and dwell time for our pakcaing materials before we apply it in production line. Labthink HST-H3 Heat Seal Tester is a laboratory heat sealer to determine the seal temperature, pressure and dwell time to meet a specific seal strength and product efficiency requirements. So this instrument is always used with a seal strength tester.
This heat seal tester adopts digital P.I.D temperature control technology which ensures the preset temperature to be reached rapidly without any fluctuation. and it is controlled by micro-computer with LCD, PVC operation panel and menu interface for convenient operations.
The instrument adopts the specially designed heat sealing jaws, which completely conform to multiple national and international standards.
For safety operations, this seal tester is equipped with pedal switch, as well as as well as anti-scald design
