The Ohaus General Purpose Scale Bases are rugged, precision manufactured,
and, consists of a stainless steel platform, an Aluminum structure,and an anodized
Aluminum load cell. These scale bases are designed to interface with Ohaus
electronic indicators and work with other compatible indicators as well.

All Ohaus bases are ruggedly built with overload protection to take the rough
handling encountered in a busy industrial environment, yet remain highly precise.
They meet NIST Handbook 44 Class III and Consumer and Corporate Affairs
Canada General Class requirements for legal for trade applications.
