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.

🔍 Key Features: Elastic error ≤ ±0.5% — accurate linear viscosity measurement; fatigue life ≥ 10⁷ cycles — long service life; wide temperature range -40℃ ~ +150℃ — suitable for laboratory and industrial environments; customizable cross-section (thickness 0.1–1.0 mm) — precise control, matches original specifications.

Q: Which viscometers are compatible with this hairspring?
A: The TAOMSUN hairspring series fits Brookfield LV/RV/HA/HB full series and domestic NDJ-1, NDJ-4 rotational viscometers. Please provide the instrument model or original spring parameters for precise torque matching.

Q: How to choose between beryllium copper and stainless steel?
A: Beryllium copper (QSn) offers good elasticity and anti-electromagnetic interference for regular laboratory use; 316L stainless steel provides higher strength and corrosion resistance for food, chemical and other special environments.

Q: Can replacing the hairspring restore accuracy after aging?
A: Yes. The hairspring is the core elastic component; elastic decay after long-term use causes reading drift. Replacing it with a new hairspring matching original specifications effectively restores measurement accuracy.

Q: Can non-standard torque values be customized?
A: Yes. TAOMSUN supports custom torque values within 10–200 g·cm for special fluid measurement or non-standard instrument conversion.

Q: What is the lead time for custom orders?
A: Standard items are kept in stock and ship within 1–3 days. Custom products typically take 10–25 working days depending on complexity.
