The PC500-L combines a patented Multiple Probe Maximum Differential Bubble Pressure method with full automation.

Unlike manual SensaDyne models, the PC500-L features automatic calibration (AutoCal) and user-selected, computer controlled, flow rate settings to automatically produce an entire dynamic curve (DynaCurve). It can also be used at a user-specified Surface Age for intermittent or continuous measurements.

Additional features of the PC500-L include automatic surface age measurement and the ability to make measurements under pressure up to 225 psi, making this instrument ideal for polymer manufacturers, as well as for aerosols and liquefied gases.

Like all SensaDyne Models, the PC500-L fully meets ASTM Standard D3825-90, and is completely independent of probe depth of immersion, and changes in ambient pressure, and is unaffected by foaming and surface contamination.

Features:

• Computer Controlled Flow Rate: Max: 40+Bubbles/Second, Min: 1 Bubble/2 Min.
• Automatic Calibration (AutoCal) for Surface Tension and Temperature. 
• Independent Large and Small Orifice Mass Flow Controllers.

• Advanced Software Peak-Detection; Accuracy within +/- 0.1 Dynes/Cm.
• Independent of Probe Immersion Depth.
• Unaffected by Foaming or Surface Contamination.
• Pressure Testing Capability to 225 psi.
