Hegewald & Peschke Inspekt Duo Dual-Column Universal Testing Machine

Overview

The Hegewald & Peschke Inspekt Duo is a dual-column, benchtop universal testing machine engineered for precision mechanical characterization of materials across research laboratories, quality control environments, and industrial R&D settings. Based on the fundamental principles of quasi-static axial force application—governed by Hooke’s law and standardized load-displacement transduction—the Inspekt Duo delivers traceable, repeatable mechanical property data in tension, compression, bending, shear, and tear modes. Its modular architecture integrates a high-rigidity dual-column frame with optimized lateral stiffness and minimal deflection under load, ensuring metrological integrity per ISO 7500-1 Class 1 requirements. Designed and manufactured in Germany, the system adheres to stringent European engineering standards and is calibrated against national metrology institute-traceable reference loads. The machine’s compact footprint and low center of gravity enable stable operation on standard laboratory workbenches—even in shared or space-constrained facilities—while its elevated test zones (1025 mm and 1325 mm options) accommodate high-elongation specimens such as elastomers, foams, and fiber-reinforced composites without compromising alignment accuracy.

Key Features

• Brushless, gearless drive system delivering smooth, low-vibration motion with extended service life and minimal maintenance intervals
• Optimized torque-frequency profile enabling quiet operation at ≤65 dB(A), suitable for open-plan labs and cleanroom-adjacent environments
• High-precision load cell with resolution down to 0.4% of full-scale capacity, certified to EN 10002-2 and ASTM E4 for force measurement uncertainty
• Ergonomically configured control panel with tactile feedback and intuitive navigation—fully compatible with gloved operation in production or controlled environments
• Modular crosshead travel configuration supporting user-defined displacement control, force control, or strain-controlled ramp-hold profiles
• Large base plate (≥600 × 450 mm) designed for accessory mounting, tool storage, and specimen staging—eliminating need for auxiliary work surfaces
• Integrated safety functions including hardware-limited overload cutoff, real-time fracture detection via load drop algorithm, and programmable auto-return post-test

Sample Compatibility & Compliance

The Inspekt Duo accommodates a broad spectrum of material classes—including thermoplastics, thermosets, elastomers, metallic alloys, thin-gauge metals, textiles, nonwovens, foils, springs, and composite laminates—across standardized geometries defined in ISO 527, ASTM D638, ISO 178, ASTM D790, ISO 14130, and ASTM D412. Its dual-height test space supports both conventional tensile bars and vertically extended configurations required for rubber elongation (>500% strain) and creep compliance testing per ISO 899-1. All mechanical and electrical subsystems comply with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), and force measurement traceability is maintained through factory calibration certificates aligned with DIN EN ISO/IEC 17025. Optional accessories—including extensometers (contact and non-contact), pneumatic and wedge-action grips, environmental enclosures, and thickness gauges—extend conformance to ISO 5725 (accuracy and precision) and support GLP/GMP audit readiness.

Software & Data Management

LABMASTER software—available as an optional module—provides full test sequence definition, real-time parameter monitoring, and automated report generation compliant with 21 CFR Part 11 requirements. It supports multi-step test protocols (e.g., cyclic loading, relaxation, creep hold), digital signature workflows, electronic audit trails, and secure user role management (administrator, operator, reviewer). Raw data export is available in ASCII, CSV, and XML formats; stress-strain curves are annotated with ASTM/ISO-compliant metadata (modulus, yield point, ultimate strength, elongation at break). Integration with LIMS platforms is enabled via OPC UA and RESTful API interfaces. All calibration events, user actions, and instrument state changes are timestamped and cryptographically logged to ensure full data integrity and regulatory defensibility.

Applications

• Mechanical qualification of injection-molded plastic components per ISO 10350 and automotive OEM specifications (e.g., VW 50185)
• Elastomer characterization for medical device tubing and seals—including hysteresis loop analysis and Mullins effect quantification
• Cyclic fatigue and creep behavior assessment of polymer matrix composites used in aerospace primary structures
• Spring rate verification and set-point validation for precision micro-springs in MEMS assemblies
• Tensile strength and elongation profiling of nonwoven fabrics in hygiene and filtration applications
• Quality gate testing of metal foils and battery electrode coatings under controlled humidity conditions (with optional environmental chamber)
