The AccuProbe Mini Hydrometer is ideally suited to Nano aquarium use and smaller aquarium set ups.
Accurate to +/- 0.001 specific gravity & salinity (PPT) measurements
Durable construction.
Each AccuProbe Hydrometer is individually calibrated
Temperature compensated for water between 20 to 30 Degrees Celsius
Directions:
Before first use fill with seawater and allow to stand for 24 hours to season the measurement needle.
Slowly submerge hydrometer into the aquarium water until the fill line is reached.
Place hydrometer on a level surface to read scale at pointer tip.
Avoid air bubble adherence to the pointer as this will result in inaccurate higher readings. Tap hydrometer gently with finger to dislodge any air bubbles.
The recommended specific gravity range for most marine aquariums is 1.020 to 1.023
Rinse with freshwater after use.
Made in the USA
