Wide viscosity range from 3 to 50,000 poise
Accuracy better than ± 2%, repeatability better than ± 0.75%
Can operate in constant temperature oil bath from -20°C to 100°C (up to 160°C for high temperature model)
Suitable for opaque and transparent fluids
Reusable/disposable sample tubes and balls
Results can be transmitted to host computer or optional printer via an RS-232 serial interface
Can display results in poise, centipoise, stokes, or centistokes
Models DV-4, DV-4X4, and DV-8 can test multiple samples simultaneously
DV-4X4 can test multiple samples at two different temperatures simultaneously
The falling-ball method of measuring viscosity is known for its ease of operation and extreme accuracy. This instrument greatly enhances the method through automatic electronic ball sensing and microcomputer control.
The viscometer can measure both transparent and opaque fluids. The plastic sample tubes and steel balls can either be cleaned and reused, or disposed of.
The test stations are designed to be immersed in an oil bath to maintain a constant temperature. Both four tube test stations with the model DV-4X4 are designed to be immersed in two separate oil baths so that viscosity can be measure at two different temperatures simultaneously.
