ISBT2 Trimble Digital Level Accessory Barcoded Invar Rod Staff 2m for DINI Series Level

Model: ISBT2

Specification:

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.

Invar staff with Barcode is used to accurately determine differences in elevation. It is an essential accessory to digital levels and allows them to measure the height and the distance to the leveling rod at the press of a button.

With a rigid aluminum body, the invar staff features and invar tape tensioned by soft spring to ensure that it doesn’t expand or contract with temperature changes. It has a length of two meters or three meters and two attached handles for stable positioning. The barcode staff also has two circular bubbles for superb leveling precision in various industrial applications.

To electronically read the staff, make sure the invar staff with barcode is facing the digital auto level. The height of the staff where the level beam crosses the leveling rod will be shown on a digital display. This process greatly eliminates human error and increases accuracy.

Features:

1. Superior graduation accuracy and high quality image of stripes.
2. Body of the Invar staff made of rigid aluminum profile with anodized surface. It makes sure it is not easy to get deformed in the process of measurements and very convenient to carry.
3. Invar tape seated in a protection groove of staff profile and tensioned by soft spring to compensate extension coefficient of staff profile.
