Kit for determining the density of air

The set is dedicated to determining the density of air. Consists of
2 cylindrical sample masses, designed for use in MYA microbalances, XA/3Y & XA/X analytical balances with 0.01 [mg] of
precision.
Different types of scales use different scale kit models
density determination:
For MYA microbalances:
- diameter 8 × 12 mm of stainless steel
- diameter 12 × 16 mm of aluminium
For XA.3Y & XA/2X scales:
- diameter 34 × 40 mm of aluminium
- diameter 24 × 28 mm of stainless steel
