What Makes the Model 800 Viscometer Unique?

The Model 800 Viscometer has been around for years. It’s the workhorse of laboratory and field rheological testing. But why is it so popular? Why do so many people prefer it to the competition?

  1. A lighted dial. It may not seem like much, but the tiny light inside the case illuminates the dial and makes it much easier to read. It is especially helpful in situations where ambient lighting is less than optimal. Whether it’s the glare from the sun or the gloom of a dark lab, the dial is always easy to read.
  2. Universal voltage. All of the electrical components of the Model 800 operate exclusively on DC power. What does that mean to you? It means you can plug it in almost anywhere. The included power supply accepts between 100 and 240 volts of AC power. But the best part is the frequency. Whether you are operating on 50 Hz or 60 Hz, the power supply converts it to DC. We even offer a special 12 volt adapter for use in the cigarette lighter in your car or truck.
  3. Threaded rotor. Have you ever run a test with a wobbly rotor? The rotor on the Model 800 is threaded. It mechanically attaches to the unit the same way every time. And it stays tight throughout the entire test.
  4. No gearbox. Gears are complicated and messy. They wear out easily and they are prone to jamming and locking. The model 800 has no gear box. It’s just a motor and a belt. There’s no need to switch gears to change speeds; simply turn the knob. And it’s much easier to maintain and repair. Fewer moving parts means fewer problems to fix.
  5. Speed control. The Model 800 uses a stepper motor to drive the rotor. Stepper motors have very precise speed control. While you are testing, the motor control board is constantly monitoring the speed and making adjustments. So you always know that your rotor is turning at the right speed.
  6. Extra speeds. They say less is more. But at OFITE, we disagree. We believe more is more. So instead of offering only 6 speeds, our viscometer offers 8. The standard speeds of 600, 300, 200, 100, 6, and 3 RPM are suitable for most testing on drilling fluids. But for testing cement you need two extra speeds: 60 and 30 RPM. By including all 8 speeds, the Model 800 becomes a more versatile instrument.
