RM100 Plus High Shear Rate Viscometer

TS 5833 EN ISO 3219 – Determination of viscosity using a rotational viscometer at a defined shear rate
TS 6126 EN ISO 2555 – Determination of apparent viscosity by the Brookfield method
TS EN ISO 2884-1 – Paints and varnishes – Determination of viscosity using rotational viscometers – Part 1: Cone and plate viscometer operated at high shear rate
TS 5809 – ASTM D 562 – Rotational viscometer for the Krebs-Stormer (KU) method

The RM100 Plus Viscometer is a professional rotational viscometer designed for true viscosity measurements at high shear rates in accordance with ISO 3219 (DIN 11-22-33). It delivers high-precision performance for industrial quality control and R&D applications.

Thanks to its modular design, the instrument can be configured to operate with ASTM D562 / TS 5809 (Krebs-Stormer), ASTM / ISO 2555 (RV), and MS-BV 1-1000 measuring systems. In addition, it can be converted into an ICI Cone & Plate viscometer when used with the EVA-CP temperature-controlled stand.

With rotational speeds of up to 1500 rpm, the RM100 Plus enables measurements at shear rates exceeding 10,000 s⁻¹, making it ideal for evaluating materials under high-shear conditions.

The RM100 Plus combines modern springless measurement technology with a robust mechanical design to provide highly accurate and repeatable viscosity measurements. This advanced construction minimizes the influence of environmental conditions while ensuring stable and reliable data through precise torque measurement.

User-Friendly 7” Touchscreen Display and High Torque Capacity

The RM100 Plus features a 7-inch touchscreen that allows all measurement parameters to be displayed simultaneously, enabling users to monitor and control the testing process with ease.

Key display features include:

Simultaneous display of multiple parameters
Intuitive user interface
Fast setup and real-time data monitoring

Its high torque capacity enables the RM100 Plus to measure coatings with viscosities above 141 KU, a range beyond the capability of standard Krebs viscometers. Through non-standard extrapolation methods, measurements up to 250 KU can also be achieved, providing exceptional flexibility for industrial applications.

Integrated Temperature Monitoring

The instrument is equipped with an integrated temperature sensor that allows direct monitoring of sample temperature during testing. This feature is particularly valuable for temperature-sensitive materials, ensuring more accurate viscosity evaluations.

The RM100 Plus Viscometer is supplied as standard with a laboratory stand and integrated temperature sensor. Measuring systems such as Krebs, RV, and Cone & Plate can be selected separately and integrated according to application requirements.

LR Version for Low Viscosity Applications

A low-torque LR version is available for highly sensitive measurement of very low-viscosity products. This configuration provides improved accuracy when working in low-viscosity ranges and is particularly beneficial for laboratories requiring precise low-shear measurements.

Applications

The RM100 Plus Viscometer is widely used in:

Paint and coatings industry
Chemical manufacturing
Research and development laboratories
Quality control departments
Ink and varnish production

The RM100 Plus Viscometer combines multiple measurement systems on a single platform, offering exceptional flexibility and reliability for both laboratory and industrial applications. All models are supplied with a calibration certificate, ensuring traceable and dependable 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. Measurements can also be performed with the RM100 Touch using ISO 3219 (MS-DIN-11-22-33), ISO 2884-1 ICI Cone & Plate, and MS-BV1-1000 systems.

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.
