hydrometer for determining the salt content in the aquarium water
precise measurements at 15 cm below the water surface
tips for use:
before using for the first time, we recommend placing the hydrometer in distilled water for about 12 hours.
cleaning:
crystallization of the salt will occur within the hydrometer after the measurement, these residues will affect future measurements. For this reason, clean the hydrometer with lukewarm water after each use.
