Invar Staff Rods Introduction
Invar Grade Rods are used in land surveying when first-order
high-precision elevation leveling is to be performed. The Grade
Rod, also known as Leveling Rods and Leveling Staff are made of
Invar which is a nickel–iron alloy notable for its uniquely low
coefficient of thermal expansion. The name "Invar" comes from the
word invariable, which refers to its relative lack of expansion or
contraction with temperature changes which directly lends itself to
making the most reliable rod for measuring elevation changes in
land.
Leosurvey Invar Rods Features

- Invar tape seated in a protection groove of staff profile and
tensioned by soft spring to compensate extension coefficient of
staff profile.
- Foot plate of chrome-alloy; hardened, smooth and ground.
