ASTM 100 Hydrometer Low Surface Tension, 600 - 1100 kg/m^3

The American Society for Testing and Materials (ASTM) Specification E 100 describes hydrometers using the API (American Petroleum Institute) scale and others in Specific Gravity and Density. All hydrometers can be supplied with UKAS certification, certificate traceable to recognised national standard or statement of conformity, if required.

Key Features
