DV1 Digital Viscometer

DV1 Digital Viscometer:

The DV1 Digital Viscometer is a standout due to the continuous sensing capability for rapid viscosity measurement. There is a choice of 18 different speeds to assist in measuring viscosity and temperature simultaneously. Data can easily be sent to a printer or PC due to the timed measurement function and optional software allows the DV1 to collect, analyse and record test date also.

Wingather SQ Software:

The optional Wingather Software is an easy way to gather data and plot graphs whilst creating a permanent test record. There are key features and benefits that enhance operator versatility when performing viscosity tests using this software. These benefits include multiple test mode to increase data collection, follow up events such as analysis to calculate yield stress and plastic index, automatic sample numbering, graphing up to 20 data sets concurrently and data export to a spread sheet format.

Torque Measurements and Applications:

LV:

The thinnest materials can be measured as it is for low viscosity materials. Examples of low viscosity materials include inks, oils, and solvents.

RV:

This is for medium viscosity materials higher than those measured with an LV torque. Examples of medium viscosity materials include creams, food, and paints.

HA:

Higher viscosity materials can be measured with HA torque. Examples of these higher viscosity materials include gels, chocolate, and epoxies.

HB:

This is for even higher viscosity materials than those measured with a HA torque spring. Examples of this include asphalt, caulking compounds, and molasses.
