Heated Viscometer

Heated ViscometerProduct Code: FG-K1-200-KW

The Heated Viscometer is suitable for testing viscosity of both residual fuel & 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 is 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 Parker Kittiwake Heated Viscometer:

  • Monitors changes in lubricating oil viscosity reporting in cSt @ 40°C, preventing costly engine and machinery failures
  • Verifies correct fuel grade or blend has been delivered and acceptability for storage, pumping and purifiers
  • Estimates the combustion performance (CCAI).
  • Correct density from 50°C. to kg/m³ @ 15°C in vacuo

The Heated Viscometer is extremely rugged and ideal for harsh industrial application. 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 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.

The Parker Kittiwake Viscometers have been proven to be as accurate as laboratory methods. Click this link to view an independent report from a leading analysis laboratory.
