Description
Ubbelohde viscometer III is a precision capillary instrument for kinematic viscosity determination in the measuring range 200–1000 mm²/s, with capillary constant K = 1. It is intended for standardised laboratory measurement of Newtonian fluids, including oils, intermediates and polymer solutions, where reproducible flow-time data are essential. Compliance with DIN 51562 Part 1 and ISO 3105 ensures that results remain comparable with established viscosity methods in quality control and research environments. Every unit is supplied with a factory calibration certificate, supporting documented accuracy for routine analytical work. The instrument from manufacturer Irmeco fits conventional Ubbelohde setups and thermostatic baths used in petrochemical, materials and general analytical laboratories. Delivered as one piece with a net weight of 0,1 kg, it offers a compact, defined measuring range for daily viscosity workflows. This capillary viscometer helps laboratories obtain consistent kinematic viscosity values according to recognised international standards while remaining straightforward to integrate into existing measurement procedures.

Questions about Viscometer
What is this article?
Viscometer is the article on this page. Luminix Health distributes Irmeco for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Lab instruments.
A capillary viscometer times the flow of a liquid through a tube. A rotational viscometer twists a spindle in the liquid. Both need a stated temperature. Kinematic and dynamic viscosity are different numbers. The capillary size has to put the flow time in the range the method allows.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
