Table showing kinematic viscosity (cSt) of different mineral oils at specific temperatures
ISO 15, 22, 32, 46 and 68 based on typical figures for the Esso Nuto range of HM
oils. ISO 37 based on Shell Tellus HM oil.
Calibration
Recommended period between calibrations is 12 months. Maximum period between calibrations is 36 months.
Unit accuracy may be affected by operating cycle, fluid condition or extended periods between recalibrations.
Accessories
A range wide range of accessories are available from Webtec or your local distributor. These include pressure
transducers, high pressure temperature sensors adaptors, cables and remote displays.
