HARKE HK-2450 Multi-Functional Tribological Tester

Overview

The HARKE HK-2450 Multi-Functional Tribological Tester is an engineered solution for quantitative static and kinetic coefficient of friction (COF) measurement, designed in accordance with the fundamental principles of tribological mechanics—specifically, the direct force-balance method under controlled normal load and relative sliding motion. It operates on a precision servo-driven linear actuation system, enabling reproducible, low-noise displacement control across a continuous speed range from standstill to 100 mm/min. The instrument integrates high-fidelity load sensing (with selectable full-scale ranges up to 30 N and resolution traceable to 0.05% FS), real-time position feedback, and synchronized data acquisition—ensuring compliance with internationally recognized test protocols for surface interaction characterization. Its architecture supports both ASTM D1894 and ISO 8295 methodologies, making it suitable for routine quality control in regulated manufacturing environments as well as comparative research in material science laboratories.

Key Features

• Embedded real-time operating system enabling remote firmware updates, diagnostic logging, and network-based maintenance via standard Ethernet interface
• Dual-mode friction evaluation: simultaneous acquisition of static COF (breakaway force) and kinetic COF (sustained sliding resistance), plus peel adhesion mode for laminated structures
• High-stability stepper-servo drive with closed-loop position control and programmable acceleration/deceleration profiles
• True-color TFT LCD touchscreen (7-inch) with intuitive GUI for parameter setup, real-time curve visualization, and instant result display
• Patented film-clamping mechanism ensuring uniform contact pressure distribution and eliminating edge slippage during thin-film testing
• Onboard historical data storage with timestamped records, exportable via USB or RS-232; integrated micro thermal printer for immediate hard-copy reporting
• Redundant safety architecture including hardware current-limiting circuits, software-defined force/torque cutoff thresholds, and emergency stop interlock logic

Sample Compatibility & Compliance

The HK-2450 accommodates specimens ranging from ultra-thin polymer films (≥12 µm) to rigid substrates such as metal plates, brake linings, rubber composites, and wood veneers—up to 30 mm in thickness. Its modular stage design allows rapid reconfiguration for flat-sheet, curved-surface, or irregular geometry testing. All mechanical and electrical subsystems conform to IEC 61000-6-2 (EMC immunity) and IEC 61010-1 (safety requirements for laboratory equipment). Test procedures align with GB/T 10006 (Chinese national standard for plastic film friction), ISO 8295 (plastics—determination of coefficient of friction), and are fully compatible with GLP documentation workflows when paired with HKCOF software audit trails.

Software & Data Management

The proprietary HKCOF system software provides full instrument control, automated test sequencing, and ISO/IEC 17025-aligned data integrity features—including electronic signatures, user-level access permissions, and immutable audit logs compliant with FDA 21 CFR Part 11 requirements. Raw force/displacement/time datasets are stored in CSV and HDF5 formats; trend analysis tools support statistical process control (SPC) charting, batch comparison overlays, and COF hysteresis loop quantification. Data export modules integrate natively with LIMS platforms and Microsoft Excel for further statistical modeling.

Applications

This tester serves critical roles across multiple industrial sectors: evaluating slip resistance of packaging films (e.g., BOPP, PET, PE laminates) per food and pharmaceutical packaging specifications; assessing brake pad–rotor interface stability under varying humidity and temperature preconditioning; characterizing wiper blade–glass interaction dynamics for automotive OEM validation; quantifying conveyor belt–product traction in logistics automation R&D; and supporting academic studies on biomimetic surface texturing effects on frictional anisotropy. Its versatility extends to emerging applications such as triboelectric nanogenerator (TENG) material screening and carbon-based electrode interface wear profiling.

FAQ

What standards does the HK-2450 comply with for COF testing?
It meets GB/T 10006 and ISO 8295 for plastic film and sheet materials, and its mechanical design satisfies IEC 61010-1 for electrical safety in laboratory use.
Can the instrument perform tests at elevated temperatures?
Standard configuration operates at ambient temperature; optional environmental chamber integration (−20 °C to +80 °C) is available upon request with thermal isolation and calibration traceability.
Is third-party calibration certification included?
Factory calibration is performed using NIST-traceable deadweight standards; ISO/IEC 17025-accredited calibration certificates are available as an add-on service.
How is data integrity ensured during long-duration wear experiments?
HKCOF software implements cyclic memory buffering, automatic file versioning, and CRC-32 checksum verification for all acquired datasets.
Does the system support custom test protocols beyond standard COF measurements?
Yes—via scriptable test sequences using HKCOF’s built-in Python API extension module, enabling conditional logic, multi-step loading profiles, and external sensor synchronization.
