NASA Ames Balance Inventory

NASA Ames has Internal and Semi-Span Balances. The following tables include all the balances in the Ames Inventory. Contact us to find out the status of any of the listed balances. Tables of Dimensions for Ames Internal Balances and gage resistances and lead lengths for Ames Balances are also provided.

Note: Every effort is made to keep these tables current and correct. However, customers and users of Ames balances should verify values from personnel at Bal Cal Laboratory.
