Sensadyne Fluid Surface Tensionmeter

Model PC500-LV Fully Automated High Performance


The PC500-LV uses a patented Maximum Bubble Pressure, Viscosity Compensated method for measuring both Dynamic & Static Surface Tension. This method fully meets ASTM Method D 3825-90, with no correction factors. All measurements are calibrated against known standards. The method is completely independent of probe depth and ambient pressure, and unaffected by foaming or surface contamination.


  • Automatic Calibration, temperature corrected, water and ethyl alcohol standard tables.
  • Viscosity Compensated design to correct for High Viscosity and High Solids Fluids
  • Automatic Surface Age Measurement in real-time. No supplemental calculations required
  • Pressure Testing From Ambient to 225 psi, with supplemental pressurized vessels and reactors
  • Automated Mass Flow Controllers. No manual flow adjustments
  • Computer Controlled Flow Rates for precise measurement and repeatability
  • Expanded Dynamic Flow Range from Milliseconds to Minutes, the widest range on the market
  • Precise Differential Flow Settings. All probes have individual Mass Flow Controllers
