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. Avoid air bubble adherence to the pointer as this will result in inaccurate, higher than normal readings. Should air bubbles collect on pointer, GENTLY tap hydrometer to completely dislodge them before taking your reading.
