Planimeter

For accurate measurement of indicator P/V diagrams

Planimeters types PT1 and PT2 are perfect tools for accurately measuring indicator diagrams.  Simply trace the lens along the diagram.

You only need to set the centre of the tracing lens on the engine’s P/V diagram and trace it along the curve.  On completion you can easily calculate the indicated power.

The planimeters are delivered in solid instrument cases to ensure safe handling and maintain accuracy.
