Heated Viscometer Data Sheet

Descarga hoja de datos del producto


The Heated Viscometer is suitable for testing viscosity of both residual fuel and lube oil from a wide variety of applications including diesel engines, gas and aviation turbines, gear boxes, hydraulics and marine fuels. Testing viscosity of fuel oil is important for verifying the correct grade of fuel delivered, for calculating combustion performance, plus adjusting of fuel handling and injection systems. Viscosity of lube oil is the most important property with the correct viscosity providing optimum film strength in system clearances, with minimum friction losses and leakage.

The Kittiwake Viscometers have been proven to be as accurate as laboratory methods. Click this link to view the Calibration Certificate from Saybolt, a leading independent analysis laboratory.

Features, Advantages & Benefits:

  • Monitoring viscosity gives an early warning for a range of common problems.
  • Highly accurate results with two readings are available at 40°C, 50°C or 100°C.
  • Test an even greater range of oils by changing the viscosity index or density.
  • Estimate the combustion performance (CCAI) of fuel oil.
  • Heavy duty, robust equipment – ideal for long term use with rapid results.

The Heated Viscometer is extremely rugged and ideal for harsh industrial applications. It can be purchased as a stand-alone kit, supplied in its own case, or as part of a more extensive suite of testing equipment in the Kittiwake Fuel and Lube Oil Lab, Power Plant Lab or Oil Test Centre. With readings being uniquely provided directly in centistokes, it can be used in 3 ways:

  • Unheated with automatic viscosity correction to 40°C and calculated at 100°C for lube oils.
  • Heated to 50°C for viscosity measurement of residual fuel oils.
  • Heated to 40°C for viscosity measurement of distillate fuels and lubricating oils.


  • Field testing of lubricants and fuels.
