  • Refractometer for seawater and marine fishkeeping aquarium 0-100 ppt

    This optical refractometer (salinity meter) has scales in the range of 0 - 100 ppt(0 - 10 %). The reading resolution is 1 ppt. It is designed for the measurement of seawater (marine aquaria) or very low concentrated salt solutions.
    The second scale is for reading of the salt solution density in range 1.000 to 1.070 g/cm3 (resolution 0.001 g/cm3).

    The usual salinity of the selected aqueous solutions 

    Example: Salinity 36 ppt means, that there are 36 grams of salt in1 liter aqueous solution.

    0.5 to 30 ppt

    Saline water (Seawater)

    30 to 50 ppt


    > 50 ppt


    The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale.
