Product Introduction
HST-01B Heat Seal Tester is a laboratory instrument designed to determine optimal heat-sealing parameters — dwell time, sealing pressure and sealing temperature — for plastic films, flexible composite films, plastic-coated paper and other heat-sealable materials.

Product Features

• Built-in microcomputer control with a user-friendly interface
• 6-inch high-definition color LCD touch screen for direct parameter input
• Digital P.I.D temperature control for fast setpoint reach and reduced temperature fluctuation
• Patented sealing-jaw design for uniform heating across the sealing surface
• Manual start or footswitch operation to enhance operator safety

Test Standards
The instrument complies with multiple international standards, including ASTM F2029.
