Brookfield Viscosity Standards
- 1. Viscosity Standards ...to verify calibration of laboratory viscometers/rheometers Accuracy: ±1% of viscosity value Special Order Silicone Excellent temperature stability Fluids Recommended for use with For our customers needing a nonstandard Brookfield and most other rotational viscosity or temperature range, our silicone viscometers fluids can be modified to meet most Most economical requirements. Special viscosity values and Viscosity Blends Calibrated at temperature calibrations available 25°C (77°F) upon request Minimum: 5 cP (mPa•s) Maximum: 60,000 cP (mPa•s) Blends will be within ±2% of requested value Temperature Calibrations General Purpose Silicone Fluids Minimum: 10°C (50°F) Brookfield Nominal Viscosity Maximum: 80°C (176°F) Part # cP (mPa•s) Temp °C Minimum temperature increment: 2°C 5 cps 5 25.0°C 10 cps 10 25.0°C 50 cps 50 25.0°C 100 cps 100 25.0°C 500 cps 500 25.0°C 1000 cps 1,000 25.0°C 5000 cps 5,000 25.0°C 12500 cps 12,500 25.0°C 30000 cps 30,000 25.0°C 60000 cps 60,000 25.0°C 100000cps 100,000 25.0°C High Temperature Silicone Fluids Brookfield Nominal Viscosity Part # cP (mPa•s) Temp °C Temp °F HT30000 30,000 25.0°C 77°F VisCal Kit 9,000 93.3°C 200°F The Brookfield VisCal Kit provides all the 4,500 149.0°C 300°F necessary items to verify calibration of HT60000 60,000 25.0°C 77°F your Viscometer/Rheometer.
