Key Features
- Only one device for a universal viscosity range: 5 to 70,000,000 mPas covered in a single instrument, without swapping between multiple machines
- Equipped with a high-quality, durable ball bearing in the measuring mechanism, in place of the vulnerable bearing tip used in comparable viscometers
- Large color touch-display shows viscosity, torque, speed, programme status, temperature and curve progression, with a multilingual, intuitive interface (7 languages)
- Seven color-coded spindles included as standard, fixed with a practical bayonet lock — no decoupling or special care needed when changing spindles, suited to high sample throughput and multi-shift operation
- Integrated temperature sensor (-20°C to +120°C, 0.01°C resolution); the optional VISQItherm electrical heating accessory extends measurement up to +300°C, heating samples in as little as 15 minutes
- Accuracy of ±1% of the measuring range end value, repeatability of ±0.2%, with optional battery operation for field tests and optional PC software for multi-point measurement
About the VISQI No 1 Rotational Viscometer
The VISQI No 1 from RHEOTEST, Germany, is a rotational viscometer that covers a universal viscosity range, 5 to 70,000,000 mPas, in a single instrument, so there is no need to swap between multiple machines. Its measuring mechanism uses a high-quality, durable ball bearing in place of the vulnerable bearing tip used in comparable viscometers.
A large color touch display shows viscosity, torque, speed, programme status, temperature and curve progression, with a multilingual, intuitive interface in 7 languages. Seven color-coded spindles are included as standard and fixed with a bayonet lock, so spindles can be changed without decoupling or special care, which suits high sample throughput and multi-shift operation. Accuracy is ±1% of the measuring range end value, with ±0.2% repeatability.

Rotational viscometer: frequently asked questions
What viscosity range does the RHEOTEST VISQI No 1 cover?
5 to 70,000,000 mPas in a single instrument, so you do not have to switch between multiple machines. Accuracy is ±1% of the measuring range end value, with repeatability of ±0.2%.
How are spindles changed on the VISQI No 1?
Seven color-coded spindles are included as standard and fixed with a practical bayonet lock, so there is no decoupling or special care needed when changing spindles. This suits high sample throughput and multi-shift operation.
Can the VISQI No 1 measure at elevated temperatures?
It has an integrated temperature sensor (-20 °C to +120 °C, 0.01 °C resolution). The optional VISQItherm electrical heating accessory extends measurement up to +300 °C, heating samples in as little as 15 minutes.
Can it be used for field tests or connected to a PC?
Optional battery operation supports field tests, and optional PC software supports multi-point measurement. The instrument itself has a large color touch display with a multilingual interface in 7 languages.
