Chatillon DFS 3 Series Digital Force Gauge

Overview

The Chatillon DFS 3 Series Digital Force Gauge is a high-precision, microprocessor-controlled force measurement instrument engineered for static and dynamic tensile and compressive testing in laboratory, production, and quality assurance environments. Utilizing strain-gauge-based transduction technology calibrated per ASTM E4 and ISO 7500-1 standards, the DFS 3 delivers traceable force measurements across a broad range of capacities—from 0.5 lbf (2.5 N) to 500 lbf (2500 N)—with an accuracy of ±0.1% of full scale and a sampling rate up to 30 kHz. Its modular architecture supports both handheld and fixture-mounted configurations, enabling consistent application of controlled load profiles during peel, bond, break, crimp, and insertion testing. Designed for compliance-driven workflows, the gauge meets essential requirements for GLP and GMP documentation integrity—including user-access control, audit-trail-capable configuration locking, and export-ready data formatting.

Key Features

• Full-color, high-contrast LCD display with user-selectable orientation (normal/inverted) and adjustable brightness for optimal readability under varying ambient lighting conditions
• Ergonomic, rubberized keypad with tactile feedback and context-sensitive icon mapping—each key corresponds directly to on-screen menu options for intuitive navigation
• On-device statistical analysis engine: real-time calculation of mean, standard deviation, coefficient of performance (Cpk), min/max, peak hold, and pass/fail thresholds based on user-defined upper/lower limits
• Configurable audible feedback: programmable key tones and alarm alerts for limit breaches or test completion
• Comprehensive security framework: password-protected access to setup menus, main screen lockout, and optional result masking to prevent unauthorized viewing of sensitive test outputs
• Integrated data management: automatic timestamped saving of all test records; one-touch export via USB or RS-232 to external storage or host PC
• Ruggedized housing with IP65-rated front panel sealing, ensuring resistance to dust ingress and low-pressure water jets—suitable for industrial floor environments

Sample Compatibility & Compliance

The DFS 3 Series accommodates diverse sample geometries and mechanical behaviors through interchangeable load cells and customizable test fixtures—including pneumatic grips, peel arms, and custom jigs compatible with universal testing frames. It supports standardized test methods per ASTM D903 (peel strength), ASTM D1876 (T-peel), ISO 8510-2 (adhesive bond strength), and USP (device actuation force). All units are CE-marked and RoHS-compliant. Calibration certificates traceable to NIST standards are available upon request. The device’s firmware architecture enables future validation against FDA 21 CFR Part 11 requirements when deployed with ForceTest 3.0 software in regulated pharmaceutical or medical device manufacturing settings.

Software & Data Management

ForceTest 3.0—the included Windows-compatible software—extends the DFS 3’s functionality beyond standalone operation. It provides real-time graphing of force vs. time/displacement curves, automated report generation (PDF/CSV/XLSX), multi-channel synchronization for dual-gauge setups, and configurable test method templates aligned with internal SOPs or industry standards. The software maintains a secure local database with version-stamped entries, supports electronic signatures, and logs all user actions—including parameter changes, calibration events, and data exports—for audit readiness. Exported datasets include raw sampled points (30 kHz), calculated statistics, and metadata such as operator ID, environmental conditions (if logged externally), and equipment serial number.

Applications

• Quality control of adhesive bonds, laminates, and packaging seals (e.g., blister pack peel strength, tape adhesion)
• Mechanical validation of medical devices—including syringe plunger break-loose force, catheter torque resistance, and connector retention testing
• Material characterization in R&D labs: tensile yield point detection, snap-fit engagement/disengagement forces, and spring constant verification
• Automotive component testing: gasket compression set, switch actuation force, and fastener torque-to-yield profiling
• Electronics assembly verification: button click force, flex circuit bending endurance, and heat sink retention load assessment

FAQ

What is the maximum sampling frequency supported by the DFS 3 Series?

The DFS 3 Series captures force data at up to 30,000 samples per second, enabling high-fidelity capture of transient events such as brittle fracture or rapid release phenomena.
Can the DFS 3 be integrated into an automated test stand?

Yes—via analog output (0–5 V or 0–10 V), digital I/O triggers, and bidirectional serial communication (RS-232/USB), the gauge supports synchronized operation with motorized stages, PLCs, and custom-built test rigs.
Is ForceTest 3.0 software validated for use in FDA-regulated environments?

While ForceTest 3.0 itself is not pre-validated, its architecture supports IQ/OQ documentation protocols and complies with data integrity principles outlined in FDA guidance on computerized systems. Validation packages and UAT support are available through Chatillon’s technical services team.
How is calibration maintained over time?

The DFS 3 includes built-in zero and span calibration routines. For traceable metrological assurance, annual recalibration using NIST-traceable deadweight standards is recommended—and documented calibration reports can be generated and archived within ForceTest 3.0.
Does the device support multiple language interfaces?

The DFS 3 firmware currently supports English and Spanish language displays. Additional languages may be enabled via firmware update upon customer request and regional regulatory approval.
