Chatillon DF2 Series Digital Force Gauge

Overview

The Chatillon DF2 Series Digital Force Gauge is an engineered precision instrument designed for reliable, repeatable force measurement in quality control, R&D, and production environments. Based on strain-gauge transducer technology, the DF2 delivers high-fidelity load data across tension and compression applications with a resolution optimized for manual and fixture-mounted testing. Its compact form factor—combined with dual mounting flexibility (handheld or bench-mounted via optional stands)—enables seamless integration into diverse physical property testing workflows, from packaging seal strength validation to spring rate verification and fastener torque auditing. As a U.S.-manufactured instrument distributed globally, the DF2 meets foundational metrological requirements for traceable force measurement under ISO/IEC 17025-aligned laboratory practices.

Key Features

• High-accuracy strain-gauge sensor architecture delivering ±0.1% full-scale accuracy across all standard ranges (e.g., 0.1–500 lbf models)
• Full-color, dot-matrix LCD display with 180° rotational capability—ensuring optimal visibility regardless of fixture orientation or operator position
• Multi-unit support: direct readout in ozf, gf, lbf, kgf, and SI-compliant newtons (N), eliminating manual unit conversion errors
• Configurable display modes: real-time load, peak hold (tension/compression), first-peak capture, and statistical batch averaging
• On-device password protection for critical configuration parameters—including zero offset, unit selection, and sampling rate—to maintain measurement integrity in shared lab environments
• Dual communication interfaces: native RS232 and USB 2.0 ports supporting both legacy industrial controllers and modern PC-based data acquisition systems
• Embedded multilingual firmware supporting English, Spanish, French, German, Portuguese, and Simplified Chinese—facilitating global deployment without software localization overhead

Sample Compatibility & Compliance

The DF2 series accommodates a broad range of sample geometries and mechanical behaviors through interchangeable fixtures—including hook-and-loop adapters, compression platens, pneumatic grips, and custom-threaded mounts. It complies with ASTM E4 (Standard Practices for Force Verification of Testing Machines) for periodic verification and supports routine calibration against certified deadweight standards. Each unit ships with a NIST-traceable calibration certificate documenting as-received performance at multiple points across its rated capacity. While not inherently 21 CFR Part 11 compliant, the DF2’s password-protected settings, audit-ready calibration documentation, and deterministic data output make it suitable for GLP/GMP-aligned workflows when integrated with validated third-party software platforms.

Software & Data Management

The DF2 operates independently but is fully compatible with Chatillon’s proprietary MESUR™gauge software (Windows-based), enabling real-time graphing, statistical analysis (mean, SD, Cp/Cpk), pass/fail thresholding, and export to CSV, Excel, or PDF formats. Raw ASCII data streams via RS232 or USB are protocol-transparent—allowing integration with LabVIEW, MATLAB, or custom MES/SCADA systems using standard serial command sets (e.g., “READ?”, “PEAK?”, “UNIT N”). All data exports include timestamp, unit identifier, and measurement mode metadata—supporting traceability requirements in regulated industries.

Applications

• Packaging: Seal strength, peel adhesion, burst pressure, and cap torque testing per ASTM F88, F904, and ISO 11607
• Medical Devices: Catheter push/pull force, syringe plunger resistance, and implant anchoring strength verification
• Automotive: Gasket compression set, switch actuation force, and pedal return spring evaluation
• Electronics: Keyboard tactile feedback, connector insertion/extraction, and flex-circuit bending endurance
• Materials Science: Tensile yield point of thin films, compressive modulus of foams, and bond strength of laminated composites

FAQ

Is the DF2 calibrated before shipment?

Yes—each unit includes a NIST-traceable calibration certificate covering at least three points across its full scale.
Can the DF2 measure torque directly?

No—the DF2 measures axial force only; torque measurement requires a dedicated torque sensor or mechanical lever-arm conversion with known moment arm.
What is the maximum sampling rate?

The DF2 acquires data at 1,000 Hz internally, with configurable output rates up to 100 Hz via RS232/USB for high-speed transient capture.
Does the DF2 support automatic zeroing during dynamic tests?

Yes—programmable auto-zero delay and trigger-based zeroing are available to compensate for thermal drift or fixture deflection prior to measurement initiation.
Are replacement batteries user-serviceable?

Yes—the rechargeable Li-ion battery pack is field-replaceable using standard Torx tools; spare battery kits and chargers are available as optional accessories.
