【FM-4R5 Four-Terminal Fixture Product Introduction (English Version)】
The FM-4R5 Four-Terminal Fixture is a precision measurement accessory specifically engineered for low-resistance testing using double bridge circuits, delivering high-accuracy and stable resistance measurement solutions for laboratories, industrial quality control, and material research. Featuring an optimized four-terminal Kelvin contact design, this fixture effectively eliminates the influence of contact resistance and lead resistance inherent in traditional two-terminal measurements, enabling reliable ohm-to-milliohm level resistance analysis for metallic conductors, electronic components, and composite materials.
With its split-structure configuration, the fixture incorporates isolated current input terminals and voltage sensing terminals, achieving physical separation between current excitation and voltage detection circuits. This design significantly enhances weak signal acquisition accuracy. The contact points utilize high-conductivity wear-resistant alloy coupled with adjustable pressure mechanisms, ensuring consistent electrical contact while preventing sample deformation. The open-frame architecture accommodates various sample geometries including sheets, wires, and irregular shapes, supporting thickness ranges from 0.1mm to 5mm.
Operational efficiency is prioritized through ergonomic non-slip handles and visual pressure indicators, enabling rapid sample positioning and force adjustment. The modular interface design ensures direct compatibility with mainstream double bridge instruments without requiring additional adapters. Precision-machined components undergo rigorous stability validation, maintaining reliable contact performance across environmental temperatures from -20℃ to 80℃, making it suitable for prolonged operation in demanding experimental conditions.
