• BioTek Marine Refractometers Available Now

    Aquarium Specialty is pleased to announce a new product offering from BioTek Marine, the BioTek Marine Salinity Refractometer.

    BioTek Marine Refractometer

    The BioTek Marine Salinity Refractometer measures “true” seawater salinity levels, instead of just sodium chloride (NaCl) content.  This device measures additional elements contributing to salinity which are usually unaccounted for, such as calcium and magnesium resulting in more precise, accurate results. The BioTek Marine Salinity Refractometer features full ATC (auto temperature compensation) for water temperatures ranging from 5 to 30 degrees C (41-86 degrees F).  The right side of the scale checks the Salinity levels with the range of 0-100 ppt (with 1 ppt scale divisions) while the other side gauges Specific Gravity with a range of 1.000 to 1.070 (+/- 0.001 accuracy).

    This high quality refractometer is sure to be a big hit with an affordable price of $35.99.  Click here to find out more.
