LC-NDJ-79 Analog Rotational Viscometer, 10-1 × 10^6 mPa·s (CAT#: STEM-BC-4026-ZJF)

The LC-NDJ-79 is a mechanical pointer-type rotational viscometer for measuring the absolute viscosity of Newtonian and non-Newtonian fluids. It determines viscosity by measuring the resistance acting on a rotor rotating in the sample. The high-precision mechanical dial is resistant to electromagnetic interference and is suitable for laboratories and industrial environments. A rotary speed selector allows users to switch quickly among different measurement conditions. The synchronous motor maintains stable rotor speed despite normal load or power fluctuations. The supplied Type II measurement rotor set and container support testing across a broad viscosity range. Three selectable speeds allow the instrument to accommodate samples from moderately low-viscosity liquids to high-viscosity materials. Its compact structure, straightforward controls, and mechanical design simplify routine operation and maintenance. The instrument is suitable for stable viscosity testing where direct analog indication is preferred.
