INTRODUCTION
The U.S. Solid digital rotational viscometer includes a small-sample adapter and No. 21, 27, 28, and 29 spindles for selecting sample volume and viscosity range by method. Its metal outer housing helps protect internal components during routine laboratory, formulation, and production testing. The included R2 to R7 spindles provide the standard range of 40 to 40,000,000 mPa.s.
FEATURES
- MULTI-SPINDLE KIT: Includes the small-sample adapter and No. 21, 27, 28, and 29 spindles for 7.1 to 13.5 mL samples from 50 to 10,000,000 mPa.s; standard R2 to R7 spindles are also included.
- METAL INSTRUMENT HOUSING: The machine uses a sturdy metal outer housing to help protect internal components during regular setup, adjustment, and testing in laboratories and production quality-control areas.
- CONTROLLED PERFORMANCE: Provides ±1% viscosity accuracy and ±0.5% repeatability for Newtonian liquids under controlled conditions; select the spindle and speed to maintain 10 to 90 percent torque.
- TEST INFORMATION DISPLAY: The 3.0 inch TFT color screen displays viscosity, spindle, speed, torque, temperature, and test time; timer operation and a viscosity curve support repeatable test methods.
- RECORDS AND OUTPUT: Stores up to 10,240 test records for method tracking; RS232 supports connection to a compatible computer or printer, while 100 to 240 V AC input supports use in different laboratory locations.
