Meaning and Definition

A flat, precisely level surface or instrument used as a reference or standard for testing the flatness or levelness of other surfaces.

In precise machining and metrology, it refers to a tool, typically a flat plate of granite or metal, used to check the accuracy of surface plates, machine beds, and other components.

Common Mistakes When Using “planometer”

  • Using it to mean 'planner' or 'speedometer'. Confusing it with 'planimeter' (an instrument for measuring area).

FAQ

Frequently Asked Questions

No, it is an extremely rare and highly specialized technical term used only in precision engineering and metrology.

A planometer checks flatness, while a planimeter is a device for measuring the area of an irregular two-dimensional shape.

High-grade granite or stable metals like cast iron are common, as they provide a stable, flat, and wear-resistant surface.

No, that would be incorrect. It has no relation to the verb 'to plan'. The 'plano-' root refers to a flat plane.

A flat, precisely level surface or instrument used as a reference or standard for testing the flatness or levelness of other surfaces.

Planometer is usually technical, industrial in register.
