Application and Brief Intro
HST-01 Heat Seal Tester is for the determination of the heatsealability of a surface, or sealant layer of films, laminates, composites and polymers etc. How well the material heatseals is expressed quantitatively as seal strength as a function of the sealing conditions of temperature, time and pressure. HST-01 Heat Seal Tester is professionally designed for the precise measurement of the three parameters of temperature, time and pressure in the heat seal process. HST-01 Heatsealability Tester conforms to standards of ASTM F2029, QB/T 2358 and YBB 00122003.

Principle
Place a sample between two-heated sealing jaws of HST-01 Heat Seal Tester with flat surfaces when the required temperature reaches equilibrium. The upper seal jaw, driven by a gas cylinder, is pushed down, to exert a certain pressure on the sample and remain for some time. When the preset sealing time ends, the upper sealing jaw returns to its original position and the whole heatsealability testing process finishes.

Brief introduction:
Lt-01 leak tester is designed for the examination of airproof property of packages, containers, bags, pipes. Lt-01 package air proof tester is widely used in food, beverage, pharmaceutical, daily chemical, electrical and electronic industries, etc. Lt-01 leakage tester complies with astm d3078 and gb/t 15171 standards.
The leak detection system is composed of the mainframe and the vacuum chamber. A test sample is placed into a vacuum chamber with water and the air above water level is evacuated by a venturi vacuum ejector. A great pressure difference is created inside and outside the sample and any slight leakage can be observed and identified when the sample is inflated.
Features
Lt-01 leak tester uses vacuum ejector to generate stable vacuum environment. .
The leak detection requires no electricity
High leakage test efficiency
Extra-thick perspex
Different chamber sizes available
No calibration needed
No vacuum pump required
Easy installation, start-up and operation
Low maintenance
