Hikari AccuProbe Aquarium Calibrated Hydrometer

Description

A highly accurate, easy-to-use, wide-range specific gravity meter for marine aquarium use. Designed to eliminate inaccuracy issues common with competitive quick-dip hydrometers while helping you take a water sample from a greater depth that is free of the negative impact of surface influences.

Durable Construction For Extended Life
“Dry Hands” design avoids contamination of aquarium or water
Takes a more “true” water saple at a 6 inch depth, avoiding inaccurate surface sampling
Accurate to ±0.001 specific gravity and salinity (PPT) measurements
Auto temperature-correcting design to give a temperature-corrected reading in warm water aquariums – 68°F to 85°F (20°C to 30°C)
Readings can be taken in or outside the aquarium
Self-leveling, hanging device collects perfect samples
Scientifically verified design offers the ultimate inaccuracy
