Chatillon LG Series Analog Force Gauge

Overview

The Chatillon LG Series Analog Force Gauge is a mechanically operated, spring-based force measurement instrument engineered for reliable, real-time tensile and compressive force evaluation in laboratory, production, and field environments. Utilizing a precision-calibrated helical coil spring and a robust analog dial indicator, the LG gauge operates on Hooke’s Law principles—where applied force is linearly proportional to spring deflection—enabling direct mechanical readout without external power or electronics. Designed for fundamental mechanical testing tasks—including peel strength, button pull-off, lid seal integrity, and spring load verification—the LG series delivers consistent repeatability under static and quasi-static loading conditions. Its fully analog architecture ensures immunity to electromagnetic interference (EMI), battery dependency, or software latency—making it especially suitable for GLP-compliant manual QC stations, educational labs, and regulated manufacturing lines where traceable, operator-verified measurements are required.

Key Features

• High-visibility analog dial with dual-scale graduation (metric and imperial units) for rapid visual interpretation
• Durable ABS plastic housing with ergonomic contouring for extended handheld operation and reduced operator fatigue
• Integrated mounting thread (1/4″-20 UNC) compatible with standard Chatillon test stands, motorized actuators, and custom fixtures
• Mechanically damped pointer movement to suppress oscillation during dynamic load transitions
• Calibration traceable to NIST-traceable standards; supplied with individual calibration certificate per unit
• No power source required—ideal for use in explosion-proof zones, cleanrooms, or remote locations

Sample Compatibility & Compliance

The LG Series accommodates a broad range of sample geometries and material types through adaptable fixturing—e.g., hook-and-loop grips for textiles, flat platens for packaging seals, and vise-mounted jaws for rigid components. It complies with ASTM E4 (Standard Practices for Force Verification of Testing Machines) and ISO 7500-1 (Metallic Materials — Calibration of Force-Testing Machines) for Class 2 accuracy performance. While not designed for high-frequency cyclic loading, its static accuracy meets requirements for routine pass/fail verification per ISO 9001 quality management systems and FDA-regulated device packaging validation (21 CFR Part 820). Units are supplied with RoHS-compliant materials and CE-marked for conformity with EU Machinery Directive 2006/42/EC.

Software & Data Management

As a purely analog instrument, the LG Series does not interface with digital data acquisition systems or proprietary software platforms. However, its standardized mounting interface enables seamless integration into semi-automated test setups using third-party load frames equipped with analog-to-digital converters (e.g., 0–5 V or 4–20 mA output modules). For documentation compliance, users may pair the gauge with validated manual entry protocols in LIMS or electronic batch records, supported by audit-trail-capable calibration logs aligned with ISO/IEC 17025 requirements. Optional accessories—including calibrated deadweight sets and zero-adjustment tools—facilitate in-house periodic verification per internal SOPs.

Applications

• Package integrity testing: seal peel force, tear resistance of laminated films, blister pack push-through force
• Assembly verification: snap-fit retention force, gasket compression load, hinge torque estimation (via lever-arm conversion)
• Material characterization: tensile strength of elastomeric bands, breaking load of sutures and filaments
• Educational demonstrations: Hooke’s Law validation, stress-strain relationship visualization, mechanical advantage experiments
• Field service: door latch engagement force, brake pedal effort assessment, HVAC damper actuation load checks

FAQ

Is the LG Series suitable for dynamic or impact force measurement?
No—it is rated for static and slow-ramp quasi-static applications only; peak impact forces may exceed spring elastic limits and compromise calibration.
Can the LG gauge be recalibrated in-house?
Yes, using NIST-traceable deadweights and documented procedures; however, formal recalibration must be performed by an ISO/IEC 17025-accredited lab for regulatory submissions.
What is the typical recalibration interval recommended?
Annually—or after 5,000 measurement cycles—whichever occurs first; frequency should be justified per risk assessment in GMP environments.
Does the LG Series meet FDA 21 CFR Part 11 requirements?
Not natively, as it generates no electronic records; however, its use within a validated paper-based or hybrid workflow satisfies Part 11 predicate rule requirements when paired with controlled documentation practices.
Are replacement dials or springs available for field servicing?
Yes—Chatillon offers certified spare parts kits (including pre-tensioned springs and calibrated dials) with full traceability documentation for authorized service centers.
