Model 900 Viscometer

The Model 900 Viscometer is a true Couette coaxial cylinder rotational oilfield viscometer, which employs a transducer to measure the induced angle of rotation of the bob by a fluid sample. For a fully automated Control/Data Acquisition System suitable for research applications, the Model 900 Viscometer may be connected to a computer via a serial (RS-232) port using OFITE's exclusive and field-proven Windows™- based ORCADA^® software.
