Sag Shoe Assembly
The Viscometer Sag Shoe Test (VSST) is a well site and laboratory test that measures the weight material sag tendency of field and lab-prepared drilling fluids under dynamic conditions. The VSST provides an intrinsic fluid property without regard to the conditions under which the fluid has been or will be used. As such, results must […]

Marsh Funnel Viscometer
Viscosity and gel strengths are measurements that relate to the flow properties of fluids. The Marsh Funnel Viscometer has been used for many years to obtain an indication of the relative viscosity of drilling fluids (known as Funnel Viscosity). It is calibrated to outflow one quart (946 mL) of fresh water at a temperature of […]
Double Walled Circulating Cup
The Double Walled Circulating Cup is designed to cool a fluid sample below ambient temperature while taking viscosity readings.

Shearometer Tube with Weight Support
This 20 gram shearometer tube with weight support is used for testing heavier muds and is specifically designed for testing high gel strength drilling fluids. It is common for 10 minute gels to reach 35 lb / 100 ft2. Drilling conditions and economics will determine the need to reduce gel strengths. Part Number #166-10 Instruction […]
Shearometer Kit
An alternative measuring device used in determining the gel strength of a drilling fluid is the Shearometer. The set includes two 5-gram, 3.5″ x 1.4″ hollow shear tubes and a sample cup with a graduated scale mounted in the center of the cup base. The scale measures gel strength in pounds per 100 square feet. […]
Universal Heat Cup
The OFITE Universal Heat Cup is designed for controlling the temperature of a fluid sample while taking readings with a rheometer or viscometer. Normal heat-up time is 15 minutes and the pilot light turns on during heating. Features Designed to work with the Model 900 Viscometer Can be plugged directly into the Model 900 Viscometer, […]
Thermocup with Removable Stainless Steel Cup
The Thermocup is designed for controlling the temperature of a mud sample while taking readings with a viscometer. The holes in the stage of OFITE Viscometers have been positioned to hold the heated cups at a 45° angle to the line of the instrument for better accommodation of thermometers and power cables. A removable stainless steel cup (included) makes cleaning […]
Hand Crank Rheometer
The Hand Crank Rheometer is a direct-indicating, manually operated, rotational viscometer. The instrument is powered by a hand crank, which drives the spindle through a precision gear train. The shift cam selects between fixed speeds of 300 and 600 RPM. A Knob on the hub of the shift cam determines gel strength. Features Suitable for […]
