Chatillon DFX010 / DFX050 / DFX100 / DFFX200 Digital Force Gauge

Overview

The Chatillon DFX Series digital force gauges (DFX010, DFX050, DFX100, and DFFX200) are precision-engineered handheld instruments designed for fundamental tensile and compressive force measurement in quality control, R&D, and production environments. Based on strain-gauge transducer technology, each model integrates a calibrated load cell directly into the housing—eliminating external sensor cabling and minimizing mechanical hysteresis. The series operates under quasi-static loading conditions and is optimized for single-axis axial force measurement with high repeatability and thermal stability across ambient laboratory and industrial settings (15–30 °C, <80% RH non-condensing). Unlike legacy analog spring-based systems, the DFX platform delivers digital signal conditioning, real-time zero tracking, and automatic overload protection up to 150% of rated capacity—ensuring long-term metrological integrity without recalibration drift under routine use.

Key Features

• Four standard capacity options: 10 lbf (44.5 N), 50 lbf (222.4 N), 100 lbf (444.8 N), and 200 lbf (889.6 N)—covering common mechanical testing requirements from component assembly verification to material break-point validation.
• ±0.5% full-scale accuracy certified per ISO 7500-1 Class 1 and ASTM E4 compliance protocols—validated at three points (20%, 60%, and 100% of range) during factory calibration.
• Backlit, 5-digit LCD display with 0.01 lbf / 0.01 N resolution and configurable auto-off timer (1–30 min) to conserve battery life.
• Dual power architecture: two standard 9V alkaline batteries (IEC 6LR61) providing ≥120 hours of continuous operation, or optional universal AC adapter supporting 100–240 VAC input with interchangeable US, UK, and EU plug modules.
• Multi-language UI (English, Spanish, French, German, Portuguese, Chinese) and seven selectable force units—enabling seamless integration into multinational manufacturing and academic workflows.
• Built-in peak hold (tensile/compressive), real-time tracking, and comparative pass/fail mode with user-defined upper/lower limits—supporting go/no-go inspection without external software.

Sample Compatibility & Compliance

The DFX Series is compatible with standardized mechanical test fixtures—including flat anvil, hook, clevis, and threaded adapters—enabling repeatable mounting per ASTM D412 (rubber tensile), ISO 179 (impact-modified plastics), and USP <1042> (pharmaceutical packaging seal strength). Optional ergonomic grips and anthropometric jigs extend applicability to human factors studies, rehabilitation device evaluation, and occupational biomechanics per ISO 11228-3 guidelines. All units ship with a manufacturer’s Certificate of Conformance and traceable calibration data aligned to NIST SP 250-103. Optional NIST-traceable calibration certificates (with uncertainty budget and as-found/as-left data) meet GLP/GMP documentation requirements and FDA 21 CFR Part 11 audit readiness when paired with secure data export protocols.

Software & Data Management

While fully functional as a standalone instrument, the DFX Series supports bidirectional RS-232 communication (via optional DB9 cable) for integration with third-party data acquisition platforms such as LabVIEW, MATLAB, or custom MES/QMS interfaces. Exported datasets include timestamped force-time profiles, peak values, and statistical summaries (mean, SD, min/max) in CSV format. Firmware updates are delivered via serial interface and maintain backward compatibility with existing calibration coefficients. No proprietary cloud service or subscription is required—data sovereignty remains fully under user control. Audit trails, electronic signatures, and role-based access controls are implemented externally through validated enterprise systems, consistent with Annex 11 and ALCOA+ principles.

Applications

• Quality assurance of fastener torque retention, gasket compression set, and adhesive bond strength.
• Validation of medical device actuation forces (e.g., syringe plunger resistance, catheter push-pull thresholds).
• Material science labs measuring peel adhesion (ASTM D903), tear resistance (ISO 34-1), and flexural modulus of thin films.
• Automotive supplier audits verifying clip engagement force, switch tactile feedback, and harness retention load.
• Ergonomics laboratories quantifying grip strength, keyboard key actuation, and assistive device handle loads per ISO 9241-411.

FAQ

What is the recommended recalibration interval for DFX Series gauges?

For ISO/IEC 17025-accredited environments, annual recalibration is standard; however, frequency should be risk-assessed based on usage intensity, environmental exposure, and criticality of measurement outcomes.
Can the DFX gauge be used in dynamic or high-speed testing applications?

No—the DFX Series is designed for static and quasi-static measurements only (sampling rate ≤10 Hz). For dynamic impact or cyclic fatigue testing, consider Chatillon’s higher-bandwidth DFS or TCD series instruments.
Is the NIST-traceable certificate included by default?

No—it is an optional add-on. The standard shipment includes a manufacturer’s Certificate of Conformance with basic calibration verification data.
Does the DFX support analog output or 4–20 mA signal transmission?

No analog output is built-in. External signal conversion requires third-party USB-to-analog modules compatible with RS-232 output.
Are replacement load cells field-serviceable?

Load cells are sealed and non-user-replaceable. Full unit return to an authorized Chatillon service center is required for transducer-level repair or recalibration.
