Additional Product Info


  • These oils are suitable for the calibration of all flow cups and rotational viscometers
  • Each oil is supplied with a calibration certificate traceable to national standards
  • In addition to the standard range, many other values are available, covering a wide range of applications


Two formats of calibrated Viscosity Oils are available, Sheen Viscosity Oils and Cannon Viscosity Oils, both of which have been selected to cover a wide range of applications. Sheen Viscosity Oils are specifically formulated to meet all calibration requirements and offer high quality at an affordable price. They are UKAS certified & traceable conforming to BS, DIN , ISO, IE C. Their 100% hydrocarbon based composition makes them suitable for verification and calibration of all flow cups and rotational viscometers, from low to high shear applications. Supplied in 500 ml (1.06 pint) bottle. Precision: ± 0.3%, for dynamic & kinematic viscosity. 3 ranges available:

Slip and Friction Tester


The Slip and Friction Tester is designed to measure the sliding resistance of sheet like materials including plastic film, packaging film laminates, paper, paperboard and coated surfaces.

For over 30 years, Testing Machines, Inc. has had a history of producing reliable, accurate and robust testing instruments for measuring coefficient of friction. The model 32-07 is our latest design offering advanced features for measuring and automatically calculating static and kinetic coefficient of friction.

Slip and friction testing aids in the evaluation of chemicals and additives used to create or minimize the degree of friction between two contacting test specimens.


  • Selectable speed from 5 to 50.8 cm per minute (2 to 20 in per minute)
  • Selectable travel distance from 2.5 to 30.5 cm (1 to 12 in.)
  • Load cell: 10 newtons (1 kg, 2.2 lbs)


  • Digital display, storage and editing of up to 100 readings, and selectable units (COF or grams)
  • Settable limits
  • Statistics-average, standard deviation, high/low results.
  • Report printout with built-in printer
  • RS-232
  • Static and kinetic coefficient of friction calculated in one operation.
  • Direct drive arm with unique skid control.
  • Sled-connecting mechanism ensures level pulling action.
  • Easily interchangeable sleds.
  • Full color, easy-to-read display

Krebs Viscometer


  • Range: 54-140 KU (75-1000 g.)
  • Sturdy mechanical assembly & easy maintenance
  • Easy to read speed indication
  • Good value for money
  • Standard package: Viscometer, paddle rotor,
  • 1 pint (500 ml) / Ø85 mm can,
  • Set of 7 weights (2 x 5g, 1 x 10g, 1 x 25g, 1 x 50g, 2 x 100g,
  • 1 x 200g, 1 x 500g), AC/DC 12V adapter (for digital version)


This traditional KREBS viscometry instrument uses a rotating paddle driven by falling weights to determine the paint viscosity. The viscosity value in Krebs units can be easily converted using the table supplied or by calculation by formula from the resultant value of total weight required to reach 200 rpm.

The robust and simple construction of this viscometer allows it to be used in various environments.
2 versions available: with tachometer or with stroboscope.

Digital Rotothinner™


  • Quick release chuck for rapid rotor change and cleaning
  • Multipoint calibration
  • Remote calibration key for extra security
  • Storage facility and RS232 output for printer


The Rotothinner instrument uses a disc or ball shaped rotor to determine the viscosity of the sample under test. The results are displayed on the LCD screen in POISE units.

Rotothinners allow the operator to continuously monitor the samples viscosity whilst a solvent or thinner is added. This allows quick correction factors for use in the production batch when carried out quantitatively.

The viscosity is measured using a high quality microprocessor controlled DC motor. The robust construction of the Rotothinners means that they are suitable for use as both production and laboratory instruments. Supplied with a 250ml sample tin.
