My Tank Thread
My Aquarium Showcase
Only used 4 times and I bought an Apex gold which has salinity meter and will never use this. Comes in original packaging and calibration packets, dropper and manual. Like Brand new. Paid $124.99- $85.00 Firm . Can ship US at $13.85
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.
As for calibrating the unit, all you need to do is place a few drops of distilled water on the pan and hit "zero" to calibrate it. The unit comes with a two year warranty
