Spectro Scientific MiniVisc 3000 Series – Portable Kinematic Viscometer
The MiniVisc 3000 (Q3000) Series is a portable, solvent-free, temperature-controlled kinematic viscometer designed for on-site lubricant viscosity testing. It provides fast and accurate results, solving challenges in measuring compressor and refrigeration oils that often suffer from outgassing problems with traditional viscometers.
With its patented split cell design, gases dissipate through the sides of the cell rather than bubbling through the sample, eliminating errors and providing reliable viscosity measurement in the field.
Highlights
The MiniVisc 3000 series (formerly the SpectroVisc Q3000 Series) viscometers are the first truly portable, solvent-free, temperature-controlled kinematic viscometers, providing high-accuracy measurements for easy detection of viscosity variations caused by contamination, mix-up and oil degradation. The devices were designed to determine kinematic viscosity at 40°C in the field for applications where immediate results are essential for determining the health of critical equipment.
Principle of Operation
- Uses only 60 µL of oil (about 4 drops).
- Oil flows through a 100 µm split capillary channel by gravity.
- Infrared sensors measure flow time → calculates kinematic viscosity.
- Cell is temperature controlled at 40°C ±0.1°C for consistent accuracy.
- Easy to clean: open the split cell and wipe with a pad.

The MiniVisc 3000 Series ensures maintenance teams get fast, accurate, solvent-free viscosity measurements in the field, helping industries reduce downtime, extend equipment life, and optimize oil change intervals.
MiniVisc 3000 for Compressor oils can create unique challenges when trying to measure viscosity. Dissolved gases from refrigerants, in particular, tend to bubble out when these oils are measured using traditional viscometers. This can create errors in the measurement, typically causing readings to be much lower than they should be.
One way to get around this problem is to allow the oil sample to degas before making the viscosity measurement. One major drawback is that it can take several hours or up to a day for the oil to degas sufficiently. Fortunately there’s a better way.
The Spectro Scientific Minivisc 3000 or Q3000 viscometer has a unique split cell design that allows oil to flow through the measurement cell uninterrupted by outgassing. The gas in the sample is dissipated out the sides of the cell, rather than bubbling up through the sample as it is being measured. In this brief video, Dan Walsh, Director of Applications and Technical Services, explains how this works.
