Deepsix Hydrometer

The Deep Six Sea Level Hydrometer is a tool for measuring specific gravity and salinity in aquarium saltwater.

• It features a dual scale for specific gravity (1.000 to 1.030) and salinity in parts per thousand.

• Its design allows it to take water samples from 15 cm deep to ensure accuracy by avoiding surface oil film errors.

• The hydrometer is constructed from durable materials and has clear, bold markings and a steady pointer for easy reading.
