Digital Viscometer | Rotational Viscosity Tester – NDJ-8S

Product Description:

The NDJ-8S Digital Rotational Viscometer is a precision instrument designed for accurate measurement of high-viscosity fluids in industrial and laboratory settings. With a broad measuring range of 1–2×10⁶ mPa·s and ±1% accuracy, it is ideal for testing adhesives, polymers, lubricants, paints, and more.

This model features 8 selectable rotor speeds, digital display, and RS232 interface for easy data logging to a PC or printer. It comes equipped with 4 standard rotors and supports an optional #0 rotor for ultra-low viscosity fluids.

The NDJ-8S also includes automatic scanning, an aluminum carrying case, and an optional temperature sensor for real-time temperature monitoring during viscosity testing.

Whether for quality control, research, or production monitoring, the NDJ-8S offers reliable, repeatable results with user-friendly operation.
