Brookfield Viscometers

The New Brookfield Viscometer, DV 2T Viscometer features a 5-inch color display to guide users through test creation and data gathering for fast and easy viscosity measurements. The DV2T also offers powerful new programming capabilities and results analysis including data averaging and QC limits with alarms. User instructions with multi-step test protocols can be created using the new Program Generator Software and uploaded to the DV2T through a USB Flash Drive (both included with instrument). Test Data can be recorded directly on a local printer or sent to a PC. The new user interface provides enhanced security with customizable user levels password access to comply with regulatory requirements such as 21 CFR Part 11.

• Direct display in: cP or mPa·s, % Torque, Spindle, and Speed
• Compatible with all Brookfield accessories
• NIST traceable viscosity standards available

Specifications:

• Repeatability: 0.2% of full scale range
• Torque measurement accuracy: 1% of full scale range
• 18 speeds for greater range capability (0.3 to 100 rpm)

With it's conventional oilfield rotor, bob and torsion spring, maintaining rheology history and reproducibility between instruments is easy. The BF35 maintains a constant shear rate under varying input power and drilling fluid conditions while providing drilling fluid engineers with an accurate and versatile tool. The BF35 operates on a different measurement technique than traditional standard Brookfield Viscometers. The sample is placed in the cup and the spindle/chamber combination is then immersed into the sample. When the motor is turned on, the chamber rotates while the spindle remains stationary. When the dial reading becomes stable, the torque reading is recorded and manually converted into a viscosity value in centipoise.

Features:

• Easy speed changes
• Conventional oilfield rotor, bob and torsion spring
• Adjustable table height to accommodate a variety of beaker/container sizes
• Shear stress values displayed on easy-to-read lighted dial
• Maintains a constant shear rate under varying input power and drilling fluids
• Measures viscosity of drilling muds and fracturing fluids according to established methods from the American Petroleum Institute and the ASTM
