PhysBar - A Preview

A low-cost and highly adaptable instrument to measure fluid pressure accurately and easily!

A standalone as well as PhysLogger compatible instrument to measure fluid pressure accurately and easily. PhysBar utilizes a piezo resistive sensor to accurately and continuously measure the pressure of fluids with respect to the atmospheric pressure. A Luer socket makes it compatible with tubings of several sizes, allowing different equipment to be connected with it. In-built temperature compensation adds to the reliability of readings.

While PhysBar can integrate with PhysLogger, it can also be used as an independent device with an in-built display. PhysBar, with its wide range, excellent resolution, and ease of operation, is the ideal instrument for all your steady and transient pressure measurements, in the laboratory and the industry.
