VPFlowScope Probe

Item price 0.00

The VPFlowScope® Probe is the number one measurement tool for compressed air audits and fixed installations. You can combine the probe with two display module types or a connector cap without display. With the VPFlowScope Probe you can measure virtually any compressed air system using a single instrument .



The VPFlowScope® Probe measures mass flow, temperature and pressure simultaneously. This probe can handle various diameters and measures in both directions. This makes it the ultimate compressed air audit tool used by leading auditors worldwide. Although the VPFlowScope Probe has been designed for dry compressed air, we also have a measuring probe for wet compressed air; the VPFlowScope DP.

The bright blue LCD display provides real-time information and with the built-in data logger, you can record for certain periods of time.  Combine this with our VPStudio software on your pc and you can use this information to process data, print reports and analyze where and how exactly you can save money.
