HPHTV-100 High Pressure High Temperature Viscometer

Download HPHTV-100 Datasheet In Adobe PDF Format.

The High Pressure & High Temperature Viscometer (HPHTV) consists of a metal needle with hemispherical ends falling vertically in a fluid with its longitudinal axis along the axis of a cylindrical container. A measurement of the needle terminal velocity allows a determination of the viscous properties of the test fluid. With the HPHTV the needle falling time is measured automatically by means of Hall sensors and a magnet in the needle.

Key Advantages:

Up to 2000psi and 150^oC
Large Temperature Range of Fluids
Measures Absolute Viscosity without Instrument Calibration
Better than One Percent Accuracy and Repeatability
Automatic Falling Time Measurements to 0.001 s
Microprocessor-based Console with RS-232 Interface
Automatic Needle Lifting and Dropping
