Versatile swing-arm hydrometer accurately measures both specific gravity and water temperature.
Its clever design allows periodic or continuous reading of the most important water quality parameter in saltwater aquariums.
You can measure from 1.010 to 1.030 specific gravity and 64-97°F.
The Hydrometer provides:
Measurement of specific gravity (degree of salinity) in a saltwater aquarium
A patented design which enables the device to be permanently installed inside the aquarium for continuous, real-time reading of salinity in addition to regular periodic reading
Built-in digital thermometer, ensuring the water that is being tested is at the correct temperature
Measure from 1.010 to 1.030 specific gravity and 18-36°C (64-97°F).
