B-One Plus Viscometer – Brookfield & Krebs (KU) Measuring Device

Rotational viscometer for TS 6126 EN ISO 2555 (Determination of apparent viscosity by the Brookfield method) and TS 5809 – ASTM D562 (Krebs-Stormer, KU method)
  • B-One Plus Viskozimetre - Digital Viscometer

The B-One Plus Viscometer is a professional rotational viscosity measurement instrument developed for highly precise determination of liquid viscosity. Its compliance with ISO 2555 (Brookfield) and ASTM D562 (Krebs KU) standards makes it a reliable solution for quality control and R&D applications across various industries.

Viscosity measurement provides critical data by determining a liquid’s resistance to flow, directly influencing product quality, process stability, and production control. The B-One Plus can measure both conventional viscosity values (mPa·s / cP) and Krebs Units (KU) within a single device.

Wide Measurement Range and High Accuracy

Thanks to its modern springless measurement technology, the device delivers reliable and repeatable results without being affected by ambient temperature fluctuations. The B-One Plus Viscometer offers:

  • Measurement range: 15 – 180,000,000 mPa·s
  • High-precision torque measurement
  • Stable and reliable results
  • Wide application flexibility
  • It enables analysis of a broad range of products, from low-viscosity liquids to highly viscous materials.
User-Friendly Touchscreen Interface

The 7-inch touchscreen display allows users to easily view and manage all measurement parameters. Key features include:

  • Large and clear display
  • Easy menu navigation
  • Data recording and storage capability
  • User-friendly interface

These features save time in laboratory workflows while reducing operator errors. USB connectivity allows easy data transfer, enabling the creation of quality control reports and long-term data storage.

Delivery Configurations

The B-One Plus Viscometer is available in the following configurations:

For Brookfield Viscosity Measurement:

  • Standard laboratory stand
  • ASTM spindle set (2–7)

For Krebs (KU) Measurement:

  • Special single-hand Krebs Stormer stand
  • Krebs Stormer paddle

This allows users to select the most suitable measurement system for their needs.

Low Viscosity LR Version

The low-torque LR version of the B-One Plus provides enhanced sensitivity for measuring the apparent viscosity of very low-viscosity products. This is particularly beneficial for laboratories working in low-viscosity ranges.

Applications

The B-One Plus Viscometer is widely used in:

  • Paint and coatings
  • Chemical industry
  • Cosmetics
  • Food industry
  • Pharmaceutical industry
  • R&D laboratories
  • Quality control laboratories

All B-One Plus viscometer models are delivered with a calibration certificate, ensuring reliable and traceable measurement results.

Single Device Multiple Measurement System

Lamy viscometers feature multi-method capability. With interchangeable spindles, the same unit can measure both KU values (Krebs-Stormer method) and apparent viscosity following the Brookfield method.

Springless Design

Lamy viscometers feature a springless design. This innovative construction is unaffected by ambient temperature changes and eliminates the need for precise leveling using a spirit level. It is suitable not only for high-precision analytical laboratory environments but also for demanding industrial conditions.

Kinematic Viscosity Measurement

With Lamy viscometers, kinematic viscosity measurement is also possible by entering the product density. The devices allow measurement time to be set, enabling repeatable viscosity measurements of thixotropic products.
