The Brookfield DV-E Viscosimeter Operation Manual provides setup, calibration, and measurement instructions for accurate viscosity testing.
The manual introduces the Brookfield DV‑E laboratory viscosimeter, its components, and optional accessories such as low‑viscosity adapters, sample holders, and temperature‑controlled baths. It explains the principle of rotational viscosity measurement using a calibrated beryllium‑copper spring and interchangeable spindles.
Operational guidance covers power connection, spindle and speed selection, the AUTO RANGE function, torque‑percentage monitoring, calibration with standard fluids, and troubleshooting. Safety and maintenance recommendations are also included.
| Input voltage | 115 V or 230 V AC |
|---|---|
| Frequency | 50/60 Hz |
| Power consumption | <20 W |
| Speed settings | 18 speeds from 0.3 RPM to 100 RPM |
