ISBLS3 Precise High Accuracy Invar Levelling Staff for Leica Sprinter Digital Level 3m Length

Model: ISBLS3

Specification:

Invar Rod:

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.

The essence of manufacturing Invar levelling staff is the formation of strips on the Invar tape. Leosurvey possesses advanced coding and engraved system and technology. It takes laser interferometer as length standard. The graduation of the precision Invar levelling staff is engraved in the paint coating with an interferometrically controlled laser beam, ensuring superior graduation accuracy and edge sharpness.

We can supply both barcoded staff and graduated staff for customers. Barcode marking staff is used for digital levels and graduated marking staff is used for optical levels.

So far we have supplied levelling staffs for many different levels brands like Trimble, Topcon, Leica, GeoMax, South, Sokkia, etc.

50cm 1m 2m 3m are available.
