The Hikari® Aquarium Solutions® AccuProbe™ Hydrometer measures a wide range of specific gravity and is intended for marine aquarium use.
"Dry hands" design avoids contamination of aquarium
Measures a water sample at 6" depth to avoid inaccurate surface sampling
Accurate to 0.001 specific gravity and salinity
Designed to give a temperature-corrected reading in warm water aquariums
Durable construction for extended life
Includes self-leveling hanging device
Use Instructions Before using for the first time, fill the hydrometer with saltwater from your aquarium and allow it to sit on a level surface for 24 hours to season the measurement needle. This hydrates the calibration disc to its original specs and will provide the most accurate readings going forward.
Submerge hydrometer approximately 6" below water line
When water reaches fill line, remove hydrometer and place on level surface for accurate reading
Avoid air bubble adherence by gently tapping hydrometer to dislodge air bubbles.
Read specific gravity on inside scale and salinity on outside scale.
Rinse with fresh water after each use to maintain optimum accuracy.
Cleaning Instructions Salt deposits may accumulate on pointer and will result in inaccurate readings. If salt crystallizes inside your unit, soak in lukewarm water or vinegar for 30 minutes, rinse with fresh water and air dry.
