HTHP Viscometer

For extremely high temperature and / or high pressure viscosity measurements, OFITE offers the HTHP (or HPHT) Viscometer. This fully-automated system accurately determines the rheological properties of completion fluids and drilling fluids in terms of shear stress, shear rate, time, and temperature at pressures up to 30,000 PSI and temperatures up to 500°F. An optional Chiller is available for cooling the fluid sample below ambient temperature, further increasing the flexibility of the system.

Using the exclusive ORCADA^® software, a computer novice can operate the viscometer, and yet the system is versatile enough for advanced research and demanding test parameters.
