SOM-R
  • Utilization of the Wilhelmy plate method to precisely detect the surface film pressure and to determine the oil volume in the range of μg on a test metal sheet
  • Two independent temperature control systems to ensure reliable results and high repeatability even in difficult measuring environments
  • Indication of the oil volume in mg/m2 on a LED display
  • Easy to clean Teflon-coated trough with excellent corrosion resistance
  • Easy to clean measuring probe (glass plate)
  • Periodical calibration of the balancing system can easily be done by the user
  • Step down voltage transformer to convert foreign voltages to AC100V of the SOM-R
  • Monitoring the amount of the oil coated on rolled steel, tin, or aluminum sheets
