byko-visc RT Rotational Viscometer

The byko-visc RT is a versatile and sophisticated Rotational Viscometer and the premier instrument for precise measurement results.

It features two models with a choice of three sensitivity options - low, regular, and high - perfect to easily measure viscosity from a near water-like viscosity to a very high viscosity range to even the most viscous epoxies, sealants, and pastes.

Portable Field Viscometer


Viscosity is an important material property which needs to be specified and controlled in order to optimize how a liquid flows, spreads, or levels under certain conditions. As a manufacturer, viscosity specifications need to be developed and defined by R&D for the products used in specific conditions - often customization of recipes is required. In order to ensure a stable viscosity performance in production tests need to be run daily. The new byko-visc RT provides you all the flexibility needed for any measurement task. Whether you're a professional looking to get the most accurate measurements possible or just need to know how thick your favorite paste is, byko-visc RT has you covered.

  • Two models available with three different sensitivities (low, regular and high) and optional accessories
  • Robust Design, intuitive navigation, and a multitude of control options
  • Large capacitive color touch-screen display, which includes preset buttons to quickly recall often used measuring parameters
  • Adjustable stand can easily raise and lower the viscometer head by twisting the knob on the side, allowing for appropriate ergonomics due to both counter, and operator height and preference
  • Easy snap-on spindle attachment allows you to quickly switch out spindles with no effort
  • Solvent resistant housing
  • It's ready right out of the box - no assembly needed!
  • Each test condition is recorded for detailed results analysis and review, and repeatable day-to-day and instrument-to-instrument thanks to rigorous quality control
  • ISO 17025 calibration certificate is supplied with each instrument to confirm this performance
  • In compliance with ASTM D2196, ISO 2555 and ISO1652 standards
  • Applications: Lacquers, paints, primers, resins, lubricants, pharmaceuticals, creams, lotions, liquids soaps, beverages, dressings, sauces, and more
  • Compatible with many other rotational viscometer models in terms of results, measurement parameters, and accessories, like spindles, allowing users to easily transition to a byko-visc RT system
