The digital viscometer adopts a rotary measurement principle. The motor drives the spindle to rotate at a constant speed through a precision transmission mechanism. When the spindle rotates in the liquid sample, the liquid generates a viscosity torque acting on the spindle surface. The viscosity torque is detected by a high-sensitivity sensor and processed by the built-in microcomputer system. The calculated viscosity value is then displayed digitally on the LCD screen together with spindle number, rotational speed and full-scale percentage.

Dongguan Huakai Testing Equipment Technology Co., Ltd. is a professional manufacturer specializing in reliability and environmental testing equipment, with over a decade of industry experience. Unlike trading companies or OEM resellers, we are a vertically integrated manufacturer - owning our R&D, production, and quality control under one roof.
Every Huakai product is designed, engineered, and manufactured entirely in-house, giving us full control over precision, lead times, and customization depth that most suppliers simply cannot match.
Self-Developed, Not Sourced Our in-house engineering team holds multiple patents. We develop our own control systems, thermal management modules, and test software - not dependent on third-party core components that limit flexibility.
Fast Delivery Without Compromising Accuracy Standard models ship in as little as 7--15 business days. Our streamlined manufacturing process - not shortcuts - makes this possible.
Customization That Actually Goes Deep When clients require non-standard chamber sizes, unique temperature profiles, or integration with their existing data acquisition systems, we engineer a real solution - not just a relabeled catalogue product.
Global Compliance Built In All products are CE certified and comply with IEC, ASTM, MIL-STD, and GB standards. Our chambers have helped clients pass certifications across consumer electronics, EV batteries, automotive components, aerospace, and medical devices.
After-Sales You Can Rely On Factory engineers - not third-party agents - handle all technical support. Spare parts are stocked and dispatched within 24 hours. Remote diagnostics available for international clients.
