MEASURING CYLINDER for HYDROMETER

  1. Features:

    For determining the specific gravity with a hydrometer in saltwater aquaria

    Measuring and reading the specific gravity on the scale of the hydrometer will be easy with the new Tropic Marin® MEASURING CYLINDER. The high-quality plastic measuring cylinder is transparent, has a stable base and a spout. With a height of 36 cm (14 inches), it is ideally suited to determine the specific gravity using the Tropic Marin® HIGH PRECISION HYDROMETER. It is no longer necessary to switch off the flow pump for a measurement in the aquarium; just take the monitoring of the specific gravity outside of the tank. It is really simple!

    The Tropic Marin® MEASURING CYLINDER is available as single item and as set together with the Tropic Marin® HIGH PRECISION HYDROMETER.

  2. Benefits:

    Tool for determining the specific gravity in saltwater aquaria

  3. How to use:

    NOTE: The specific gravity is temperature dependent. With increasing temperature the specific gravity decreases. Therefore, the measured water temperature should be 25 °C / 77 °F to obtain a correct result.

    Fill the measuring cylinder with maximum 400 ml saltwater (water temperature = 25 ° C/77 °F).
    The hydrometer should be dry and clean.
    Gently place the hydrometer into the water until it floats freely.
    Now read the specific gravity on the blue part of the scale of the hydrometer at the level of the water surface – NOT at the level of the meniscus, which is creeping higher at the edges!
    To avoid any distortion of future measurements, rinse the measuring cylinder well with fresh tap or reverse osmosis water to remove salt residues after each use.

    Reading the MEASURING CYLINDERDO NOT CONFUSE: The Tropic Marin® HIGH-PRECISION ARÄOMETER, which is used in German speaking countries, has a scale with a green printing and the indication Dichte/density (see Difference between density and relative density).

    We recommend different salinities for various tank types:

    Tank type Specific gravity
    at 25 °C / 77 °F
    Salinity in ‰
    (psu)
    Fish only tanks (no invertebrates) 1.023 – 1.025 ca. 31 – 33
    Reef tanks 1.025 – 1.026 ca. 33 – 35
    Shrimps 1.026 – 1.027 ca. 35 – 36
