Description
BS/IP/RF U-tube reverse flow viscometer 10 is a precision capillary instrument intended for kinematic viscosity measurements in the range 20000–100000 mm²/s with a constant K of 100. Its reverse-flow U-tube design facilitates clear observation of the meniscus when testing opaque, dark or high-viscosity samples that are less convenient with suspended-level tubes. The instrument is delivered with a factory calibration certificate and complies with BS/IP/RF as well as ASTM D445-446 and ISO 3104-3105, enabling standardised, reproducible results across different laboratories. This model from manufacturer Irmeco weighs 0,1 kg net and is supplied as one piece for use in temperature-controlled viscosity baths. It serves quality-control, research and development laboratories in the petroleum, lubricant, chemical and related industries that need accurate kinematic viscosity data for specification testing, process control and product development under internationally recognised methods.
This article is part of Viscometers, in Density & viscosity measurement.

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.
