DNA Levelling staffs

Consistent precision even under extreme conditions
 
The choice between the Professional 5000 and Professional 3000 Series is based on the application and the associated demands on consistent high precision. The Invar levelling staffs of the 5000 Series, for example, distinguish themselves through a minimal thermal expansion coefficient. The levelling staffs of the 3000 Series are made of fibreglass, or aluminium and are well suited for all common applications.
