B-One Plus Viscometer

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 is designed for viscosity measurement in accordance with ASTM / ISO 2555 (RV) and ASTM D562 / TS 5809 (Krebs-Stormer) standards.

Its modern, springless measurement technology and robust design result in an undeniably precise and reliable measuring instrument. The intuitive 7” touchscreen display makes operation easy and allows users to view all parameters simultaneously.

Delivered with either a standard laboratory stand and ASTM spindle set No. 2–7, or a dedicated Krebs measuring stand with a single-hand operation and Krebs paddle.

The new low torque LR version of the B-One Plus offers enhanced sensitivity for the measurement of low-viscosity products. All models are supplied with a calibration certificate.

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.
