First Plus

First Plus

Rotational Viscometer acc. to
TS 5833 EN ISO 3219
(Determination of viscosity using a rotational viscometer with defined shear rate)
TS 6126 EN ISO 2555
(Determination of apparent viscosity by the brookfield test method) and
TS 5809 - ASTM D 562 Krebs-Stormer (KU) method

The First Plus is designed for viscosity measurements in accordance with the ASTM / ISO 2555 standard(RV). With optional measuring systems, it also allows to measure viscosity acc. to ASTM D 562 / TS 5809 (Krebs-Stormer), ISO 3219 (DIN11-22-33) or MS-BV 1-1000.

Its modern springless technology and sturdy design ensures undeniable reliability. The FIRST Plus has a 7” touch screen and comes with a stylus. This easy-to-use screen lets you see all measurement parameters at the same time.

The First Plus has a integrated temperature sensor and it is delivered with a laboratory stand and a set of ASTM RV 2 to 7 or LV 1-4 spindles.

The First RM Plus, also has a LR Version which allows higher accuracy for determination of the appearent viscosity of low viscosity liquids.

One Instrument
Multi Measuring System

Lamy Viscometers designed and manufactured to run with different measuring systems. The First Plus is capable of measuring both appearent viscosity measurement acc. to ISO2555, ISO3219 as well as KU measurements acc. to ASTM 562 - TS 5809 Krebs-Stormer Method used in paint industry.

Spring Free Design

Lamy Viscometers does not contain any spring for torque measurements. This innovative design allows measurements without being effected by the ambient temperature and also avoids the necessity of precise leveling of the instrument. First Plus is designed for tough industrial enviroments as well as fine laboratory conditions.

Kinematic Viscosity Measurement

Lamy Viscometers allows product density input making the kinematic viscosity measurements possible. Devices lets you set measuring times for thixotropic products.
