User’s Guide:

1. Slowly place the hydrometer into the water. When testing, make sure the test water level reaches the wave scale.

2. If there are air bubbles stuck on the pointer during the product test or while putting it into the water, use a plastic stick to blow the foam to make the bubble dismiss, to ensure accurate readings.

3. Place the product in the aquarium or on the horizontal line outside the aquarium to accurately obtain the test results.

4. When any salt is on the pointer, the salinity hydrometer will not read correctly. After using the hydrometer, it should be cleaned with tap water, soak in warm water or vinegar for 30 minutes, then air dry in a cool place.
