Pressure testing machine HST-01A

temperaturemanualcomputer-controlled

Product Introduction
The HST-01A Heat Seal Tester is a laboratory instrument for determining optimal heat-sealing parameters — sealing temperature, sealing pressure and dwell time — for plastic films, laminated flexible films, plastic-coated paper and other heat-sealable materials.

Key Features

• Built-in microcomputer control with intuitive user interface and 8-inch color LCD for real-time data display
• Digital PID temperature control for fast setpoint attainment and minimal temperature fluctuation
• Independent temperature control of upper and lower jaws; patented jaw design ensures uniform heating across the sealing surface
• Touch-screen input for temperature, pressure and time; test start via manual button or foot pedal for operator safety
• Double-side heating mode and standard sealing width 330 mm × 10 mm (customizable)

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