Product Description


Product spec testing of Diesel, base oils, lubricants and fuel oils

The PSL Rheotek RUV is suitable for determining the kinematic viscosity of a wide range of petroleum liquids including jet fuel, diesel, residual fuels, base oils and formulated oils, including black oils.

Designed with product specification testing in mind, the RUV uses a standard ASTM Ubbelohde Viscometer tube. All measurements are fully compliant with ASTM D445. For each result reported, the unit requires duplicate flow times within the determinability required for the type of sample in the tube. Robust performance is the backbone of this refinery laboratory workhorse.

 The PSL Rheotek Kinematic Viscometer consists of a single or dual analyzer module, inclusive of control system, viscometer bath and up to 4 universal measuring positions.

Automated functions include:

  • Sample push up
  • Flow time determination
  • Results calculation
  • Determinability check
  • Sample Removal
  • Sample path cleaning
  • Sample path drying
