The Digital Salinity Refractometer encompasses 3 different types of user selected scales for the measurement of salt in an aqueous solution providing for a much more precise evaluation. Each scale is temperature compensated.
PSU - The newest type scale standard - Letters stand for Practical Salinity Units and is fast become the universal standard for salinity measurement
PPT - The old standard of Parts Per Thousand of saturated salt. This is the oldest of the 3 salinity measurements scales
S.G. - The current standard of Specific Gravity hydrometers and refractometers.
The Digital Salinity Refractometer is easy to calibrate and easy to read and provides highest accuracy possible for the measurement of seawater 3 specific scales.
