PCE-RVI 1 analog viscometer /
Rotational viscosity measuring device ideal for Newtonian fluids

The PCE-RVI 1 is an analog viscometer used in industrial and research applications for measuring the viscosity of liquids such as paints, varnishes, inks, pastes, adhesives, plastics, greases, and liquid food products. Under the same conditions, test results from an analog viscometer are equally accurate and reproducible as those from a digital viscometer. Thus, the analog viscometer PCE-RVI 1 offers an affordable solution for measuring viscosity during product and material testing, development, production, and quality control.

Basic operation
Prepare the liquid to be measured and place it in a glass beaker or a right-angled container with a diameter not less than 70 mm and a height not less than 130 mm. Adjust the lifting screw and immerse the spindle into the liquid until the level mark on the spindle reaches the surface of the liquid. Connect the power supply, turn on the viscometer, screw the speed knob, select the speed, and release the indicator lever. When selecting a rotation speed of 6 or 12 rpm, the final measurement value can be read when the indicator stabilizes. When selecting 30 or 60 rpm, press the indicator joystick after it stabilizes, cut off the power supply, and then read the final measurement value.

Offering adjustable rotational speed, this portable analog viscometer:

- Provides a coefficient chart above the motor housing for on-site calculations of absolute viscosity
- Uses electric power to maintain a constant speed of 6, 12, 30, or 60 revolutions per minute (rpm)
- Features a built-in level and adjustable feet to ensure accurate measurement
- Includes four different rotors or shafts (specifications 1, 2, 3, and 4)
- Comes with a protective wooden carrying case
