Technical and Scientific Equipment (TSE) presents the HST-H3 Heat Seal Tester, from Labthink Instruments. This heat seal tester seals the specimen to test the seal parameters of laminated films, coating paper and other heat sealing laminated films according to the requirements of relative standards. The seal parameters include heat seal temperature, dwell time, and the pressure of heat seal. Different melting points, heat stability, fluidness, and thickness of heat seal materials could make heat seal properties various, which result in different sealing techniques. Users can obtain a standard heat seal index by this heal seal tester.

The heat seal tester unit utilises a P.I.D digital temperature control system, which enables an even temperature across the seal surface. Advanced pressure control elements are used, and a micro-computer controls all heat sealing parameters accurately. These parameters are displayed on the LCD.
Multifold heat sealing methods are also possible, which can be customised according to customer’s requirements. The heat seal tester is highly automated, and the design of the machine guards against the possibility of scalding.

Specifications of the heat seal tester:

  • Seal temperature:    room temperature - 300°C (accuracy: 0.2°C)
