Fill an at least 22 cm / 9-inch-high glass jug or flower vase with the seawater you want to measure. Take the hw density meter and carefully insert it into your chosen measuring vessel. In accordance to get the most accurate measuring results you must ensure that the hw density meter has no contact with the be able to carry out the most exact measurement possible, the hw density meter should not have any contact with the interior wall of your measuring vessel and floats freely.
You can read off the measured value on the upper scale, at the lower meniscus (bulge of the water surface on the protruding measuring scale) of the hw density meter.
After the measurement you should rinse the hw density meter with fresh water and dry it carefully with a clean cloth. The hw density meter should be stowed in the provided protective sleeve to ensure a safe storage.
