TAOMSUN viscometer hairspring is the core elastic component of rotational viscometers, precision-machined from high-grade beryllium copper alloy (QSn) or 316L stainless steel. It converts fluid viscous resistance into a proportional torsion angle, ensuring linearity and data accuracy of viscosity measurement. Elastic stability error ≤ ±0.5%, fatigue life ≥ 10⁷–10⁸ cycles, operating temperature -40℃ ~ +150℃, compatible with Brookfield LV/RV/HA/HB full series and domestic NDJ series viscometers. OEM/ODM customization per drawing: cross-section, torque (10–200 g·cm), material and dimensions all customizable; samples available from 5–10 pieces.

TAOMSUN measures copper hairspring, which is made by cold drawing, rolling, winding, and shaping metal filaments. It is a precision elastic element that can generate reactive torque. The products cover various types such as conductive hairspring, electrical measurement indicator hairspring, mechanical instrument hairspring, tachometer hairspring, etc., with a size range of 5-300 mm. The materials available include brass strip, beryllium green copper wire, stainless steel wire, thermal bimetallic strip, brass wire, pure copper wire, and bronze wire. The balance spring has good elastic properties, small elastic hysteresis, low temperature coefficient and resistance coefficient, and has anti magnetic and anti-corrosion properties. Design and manufacture according to user requirements or drawings. Regular products will be shipped within one week. Overseas sales/technical support are provided by METICULAB (Korea).
