Wide range Specific Gravity Meter

Description:

Self-leveling, hanging device.

Hands stay dry, thus avoiding contamination of aquarium.

Takes a true water sample at 6" depth. Avoids inaccurate surface samples.

Easy-to-read and accurate to ± 0.002 specific gravity units.

Water is gently diverted to bottom plate to avoid excess bubbles.

Designed to give temperature-corrected readings in warm water aquariums (68o-85oF / 20o - 30oC).

Readings can be taken inside or outside aquarium.,

Automatically takes correct sample size by leveling off at top of dam.

Wide range of measurement.
