Universal Zero-Datum Stamping Block
Acid-resistant stainless steel plate allowing on-site stamping of the exact staff gauge zero elevation, with space for a station name or authority logo.
Key Features & Benefits
On-site elevation stamping
Enables permanent stamping of the exact gauge zero elevation directly after geodetic levelling at the site.
Station identification
Dedicated area for the hydrotechnical structure name, river kilometre, or administrator logo.
Acid-resistant stainless steel
Manufactured entirely from stainless steel, ensuring permanent legibility for decades.
Laser-cut datum designation
Clear cut-out reference system markings (e.g. EVRF2007 / npm Am / npm Kr) provide immediate visual clarity.
