Product information

This product supersedes product no: 606250

Unitor™ Heated Oil Viscometer is suitable for measuring both fuel oil viscosity & lube oil viscosity from a wide variety of applications including diesel engines, gas and aviation turbines, gear boxes, hydraulics and fuel oils.

Small, fast and reliable. Measurements can be done without heating (but corrected to 40°C) or heated to 40°C for lube oil viscosity and to 50°C for fuel oil viscosity.


  • Reports directly in cSt, repeat reading in one minute
  • Calculation of Calculated Carbon Aromaticity Index (CCAI)
  • Clear and comprehensive user instructions


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