RVI 2 V1L is a rotational viscometer used in industrial and research applications to measure viscosity according to BS, ISO and ASTM standards. Featuring a plug-and-play sensor for temperature control to help ensure accurate test results, this digital viscometer is delivered with spindles L1, L2, L3 and L4 and displays measurements in millipascal-second (mPa.s) or centipoise (cP), depending on the rotational speed and the type of spindle used.

Basic operation
Turn on the viscometer by pressing the main switch. Once the display shows the latest saved parameters (spindle and rate), press the up or down buttons to find the applicable spindle and press the enter button to select it. Next, use the up and down buttons to find the rotational speed (rpm) and press the enter button to select it. The parameter "range" informs you about the maximum measurable viscosity value of the chosen spindle and rpm. The notification "Press start" will appear. Be sure your sample is in place before pressing the start button, as the start button begins rotation of the spindle and commences measurement.
