Heat Seal Tester

Features:

Professional

HST-H3 Heat Seal Tester is based on the heat sealing method and is professionally applicable to the determination of heat seal temperature, dwell time, and the pressure of various composite films to guide industrial production. The instrument adopts the specially designed heat sealing jaws, which completely conforms to multiple national and international standards.

• Digital P.I.D. temperature control technology ensures the preset temperature to be reached rapidly without any fluctuation
• Wide range control of temperature, pressure, and time that meet various test conditions
• Manual or pedal switch, as well as the anti-scald design, provides a convenient and safe operating environment
• The instrument is controlled by a micro-computer with LCD, PVC operation panel, and menu interface
• Professional software supports remote operation for convenient data saving, exporting, and printing

Precision

HST-H3 Heat Seal Tester utilizes precision mechanical structure design. The aluminum-encapsulated heat sealing jaws ensure uniform heat spreading along the sealing surface; cylinder-controlled sealing jaws equally apply pressure upon test specimens; rapidly removable heating tube joints provide convenient operation.

• Aluminum-encapsulated sealing jaws provide even and uniform temperature for different sealing surfaces
• Dual underneath type of gas cylinders ensure stable pressure during the test process
• The heating tube joints can be easily installed or removed for rapid replacement

High-end

HST-H3 Heat Seal Tester is designed based on the HST-H6 with more intelligent functions, which is the best choice for high-end users.

• Independent temperature control of the upper and lower jaws gives multiple combinations of test conditions
• Dual underneath and closed loop-type of gas cylinders ensure even pressure of sealing surface
• The extended sealing surface can seal large or several specimens at the same time
• Equipped with pedal switch for safe test operation
• Standard RS232 port and professional software facilitate to connect with computer and data transfer

Test Principle

HST-H3 Heat Seal Tester is composed of upper and lower heat sealing jaws. Before the test, preset the heat seal temperature, pressure, and dwell time value, place the specimen in between the upper and lower jaws, and then press the start button. The whole sealing process can be finished automatically.

Test Standards

This test instrument conforms to the following standards:
ASTM F2029, QB/T 2358, YBB 00122003
