TQC sheen – ROTATIONAL VISCOMETER VR3000
The VR3000 Viscometers, models V1 and V2, are rotational viscometers for the fast determination of viscosity as specified in ISO 2555 and other ASTM standards. Instrument offers viscosity measurements which are 100% compatible with the Brookfield method and permits to carry out comparative measurements in accordance to recognized standards in quality control laboratories.
Model V1 has a RS232 interface , software ViscosoftBasic for data gathering and a temperature probe (PT 100).
Model V2 has 2 more speeds –and consequently a wider viscosity range-, bidirectional interface RS232 and optionally, software ViscosoftPlus for the automated control of viscometer and the issuing of rheological studies.
