Friction tester C620H

coefficient of frictionlaboratoryfor packaging

A laboratory tester for measuring static and kinetic coefficient of friction (COF) and peel strength on films, sheets, foils, paper, textiles and adhesive-laminated products. Combines automatic sled lifting, integrated temperature control and embedded computer control for repeatable, high-precision testing.

Product Features

• Two test modes: coefficient of friction (COF) and peel test.
• Automatic sled lifting ensures precise still time and high repeatability of COF results.
• Sliding plane and sled demagnetized with remanence detection to reduce system errors.
• Wide-range, high-precision automatic temperature control supporting tests at different temperatures (RT–100°C).
• Force measurement system from a global supplier; accuracy: displayed value ±0.5% (10%FS–100%FS) and ±0.05%FS (0%–10% of load cell range); multiple ranges available.
• Safety features: position limit, overload protection and auto reset.
• Conforms to multiple ISO, ASTM, TAPPI and GB standards.

Embedded computer controlled system

• Large touch-screen tablet for clear viewing and operation.
• User-friendly software simplifying test setup and execution.
• Supports comparative analysis of test groups and unit conversion.
• USB and network ports for data transfer and external connection.
• Optional GMP compliance.
• Labthink data security options: separation of test data and optional DataShield™ for data management and instrument networking.
