Hikari AccuProbe Hydrometer - Salt Test

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

• Takes a more 'true' water sample at greater depths, avoiding inaccurate surface sampling
• Accurate to ±0.001 specific gravity and salinity (PPT) measurements
• Self-leveling, hanging device collects perfect samples
• Scientifically verified design offers the ultimate in accuracy
