电子变速流变仪

A precision rotational viscometer designed for conveniently testing the rheological properties of drilling fluids using two modes of operation.

 

The variable mode allows continuous speed from 3 to 600 rpm, while the second mode offers settings at conventional speeds of 100, 200, 300, 600, and gel strength (3 rpm). Closed loop speed control allows accurate testing of shear thinning fluids because the speed remains locked at the desired speed throughout testing. The rpm readout resolution is 1 rpm on a digital display. The dial indication is read directly through a cover-mounted magnifier.

 

The Model 286 Rheometer utilizes a universal power supply input and will operate at either 120 VAC, 230 VAC, or 12 VDC. This instrument is not affected by frequency variations.

 

The API recommended Torsion Spring, Rotor, and Bob are supplied with the Model 286 Rheometer. A stainless steel sample cup and a plastic carrying case are also included.

 

The Rheometer Cup Heater allows measuring viscosity at elevated temperatures. Heater Cups are fitted with a removable stainless steel sample cup for easy cleaning, and are designed to fit snugly on the Rheometer base. The Thermostat control allows heating up to 200°F (93°C).
