NDJ-1 Analog Rotational Viscometer, 1-1 × 10^5 mPa·s (CAT#: STEM-BC-4018-ZJF)

The NDJ-1 is an analog rotational viscometer for measuring the viscous resistance and absolute viscosity of liquids. It is suitable for oils, paints, plastics, foods, pharmaceuticals, adhesives, and other fluid materials. The instrument supports quality monitoring and process control in production and laboratory environments. A pointer display provides direct observation of the measured viscosity value. The lifting system uses a helical rack-and-gear structure for smooth vertical adjustment. A universal joint at the rotor connection improves alignment during installation and measurement. The speed-changing gears are made from wear-resistant engineering plastic for durable operation. Standard rotors are precision-machined from imported 304 stainless steel. An optional No. 0 rotor extends the instrument to lower-viscosity measurements.
