Milwaukee Instruments Seawater (Salinity) Refractometer
List Price: $145.00
Our Price (price includes free shipping!)
You save $18.51!
The MA887 Milwaukee Instruments Seawater (Salinity) Refractometer is an optical instrument that employs the measurement of the refractive index to determine the salinity of natural and artificial seawater, ocean water or brackish intermediates. The digital refractometer eliminates the uncertainty associated with mechanical refractometers.
To use, after calibrating, you just put a sample of your water into the prism tray of the Milwaukee Seawater Refractometer. Within seconds the refractive index and temperature are measured and converted into one of three popular measurement units; Practical Salinity Units, Salinity in parts per thousand or Specific Gravity. The measurement is displayed digitally on the LCD screen.
Automatic Temperature Compensation
Battery operation with Low Power indicator
Automatically turns off after 3 minutes of non-use

Aqua Medic Refractometer
The Aqua Medic Refractometer is a precision optical instrument used to determine the salt concentration in saltwater aquaria. The exact value can be determined in seconds and can be read either as absolute salt concentration or as specific density.
Refractometers are non-electrical devices that work by measuring the refraction of light through an aquarium water sample on a glass plate. A screw driver for calibration is included.
JBJ C-Scope Refractometer w/ ATC
The JBJ C-Scope Refractometer w/ ATC is designed for testing the concentrations of saltwater by providing a direct reading of the speciific gravity and salinity in ppt. It provides a reliable refractive index and salinity readings of total dissolved solids of aqueous solutions. The refractive index is the ratio of the the speed of light in a vacuum to the speed of light in the medium (saltwater) being measured. Light is slowed by passing through saltwater, so the index of the refraction is an indication of this speed change.
You simply add a few drops of your saltwater water over the prism and focus the eyepiece under direct lighting until you see a line that divides the scale from blue and white. This line indicates the specific gravity and the salinity.
Magnified Dual Scale
. This simple integrated feature magnifies the scale over 2x compared to traditional refractometers for easy viewing.
ATC - Automatic Temperature Compensation
. Since water temperature effects salt readings, all C-scope refractometers are equipped with ATC to give the correct reading even if your water temperature isnít.
. The ability to calibrate the refractometer allows you to cross reference your readings without ever have to second guess yourself.
Deep Color Contrast
. The C-Scope was designed to provide a clear and sharp dual scale. This is accomplished with a deep color contrast between the blue and white to quickly distinguish your measurement.
