LEICA barcode invar plates for NA/DNA/LS

Invar bars are the basis for highest precision in leveling, as they change their length only marginally under the influence of temperature. The Invar bar code tape is manufactured with a precision of less than ± 0.005 mm and is suspended in the staff body by a soft spring. This effectively compensates for the expansion of the slat body due to temperature.   
For transport, we recommend wooden boxes, in which 2 slats can be placed at a time.

The delivery includes an adjustable circular bubble.
