Chatillon DFE II Digital Force Gauge

Overview

The Chatillon DFE II Digital Force Gauge is a compact, microprocessor-controlled force measurement instrument engineered for precision tensile and compressive force evaluation in quality control, R&D, and production environments. Based on strain-gauge transducer technology, the DFE II delivers high reproducibility and linearity across its calibrated range—designed specifically for applications requiring traceable, repeatable force data under ISO/IEC 17025-aligned practices. Its modular architecture supports both handheld operation for quick spot checks and integration with motorized or manual test stands for controlled, standardized testing per ASTM E4, ISO 7500-1, and USP <1042> guidelines. The gauge features real-time load visualization, directional sensing (tension vs. compression), and automatic zero stabilization—critical for minimizing operator-induced error in regulated workflows.

Key Features

• High-resolution backlit LCD display with 5-digit readout and intuitive icon-driven interface
• Dual-mode operation: continuous real-time measurement and peak capture (with separate tensile/compression memory registers)
• Programmable high/low limits with visual and audible pass/fail indicators—enabling go/no-go verification without external software
• Onboard statistical analysis: calculates minimum, maximum, average, and standard deviation from up to 100 stored readings
• RS-232 serial output compliant with standard ASCII protocol for direct connection to PCs, PLCs, or data acquisition systems
• Rechargeable lithium-ion battery providing ≥50 hours of continuous use; supports USB-C charging and battery-level monitoring
• Automatic load cell braking and direction detection to prevent overtravel and ensure consistent start-stop conditions
• Robust aluminum housing rated IP54 for resistance to dust and incidental moisture in lab and light industrial settings

Sample Compatibility & Compliance

The DFE II accommodates a wide range of sample geometries and mechanical interfaces through standardized mounting threads (10-32 UNF female) and optional accessories—including hook attachments, compression plates, probe tips, and custom fixtures. It is compatible with universal test stands (e.g., Chatillon DFS Series) and third-party systems supporting M4 or 1/4″-20 threaded adapters. Calibration certificates are provided with NIST-traceable documentation, and the instrument supports periodic verification per ISO 9001 internal audit requirements. While not inherently 21 CFR Part 11 compliant, its data export functionality enables integration into validated electronic lab notebooks (ELNs) or LIMS platforms where audit trails and user authentication are managed at the system level.

Software & Data Management

The DFE II operates autonomously but supports bidirectional communication via RS-232 for configuration and data retrieval. Optional Chatillon DF-Data software (Windows-based) enables remote parameter setup, real-time graphing, batch export to CSV/Excel, and report generation with customizable templates. All captured statistics and individual readings retain timestamps and mode identifiers (e.g., “Peak_Tension”, “Avg_Compression”). For GxP environments, raw ASCII data streams can be directed to validated third-party acquisition tools that enforce electronic signature, change control, and audit trail retention per FDA and EU Annex 11 expectations.

Applications

• Textile break strength and seam slippage testing per ASTM D5034 and ISO 13937
• Pharmaceutical tablet hardness and capsule cap removal force per USP <1217> and Ph. Eur. 2.9.8
• Consumer product button actuation force, lid opening torque, and hinge durability validation
• Medical device push/pull force assessment for syringe plungers, catheter guidewires, and packaging seals
• Adhesive bond strength verification in electronics assembly and automotive trim attachment
• Educational mechanics labs requiring portable, standards-aligned force instrumentation

FAQ

What calibration standards does the DFE II support?
The DFE II is supplied with a certificate of calibration traceable to NIST standards. Users may perform intermediate verifications using certified deadweight test kits aligned with ISO 7500-1 Class 0.5 or better.
Can the DFE II store measurements internally without a PC connection?
No—the DFE II does not include non-volatile memory for standalone data logging. All readings must be captured in real time via RS-232 or observed directly on the display.
Is the unit suitable for dynamic or high-speed force events?
The DFE II is optimized for quasi-static measurements with sampling rates up to 2,000 Hz. It is not intended for impact or shock-force characterization, which require specialized high-bandwidth sensors and digitizers.
How is direction detection implemented?
Direction sensing is achieved via dual-polarity strain gauge bridge output and firmware-based zero-crossing detection—enabling automatic distinction between tension and compression loading without manual mode switching.
Does the gauge support metric and imperial units simultaneously?
Yes—unit selection (N, lbf, kgf, ozf, gf) is configurable per session and retained across power cycles. Conversion factors adhere to SI and NIST Handbook 44 definitions.
