This highly accurate instrument employs the measurement of the refractive index to determine the salinity of natural and artificial seawater, ocean water, or brackish intermediates. A fully portable unit, this optical device is simple and quick to use - samples are measured after a simple user calibration with distilled or deionized water. Within seconds, the refractive index and temperature are measured and converted into one of three popular measurement units - Practical Salinity Units (PSU), Salinity in parts per thousand
(ppt), or Specific Gravity (S.G. (20/20)). All conversion algorithms are based upon respected scientific publications using the physical properties of seawater, not sodium chloride. The temperature in Celsius or Fahrenheit is also displayed on the large dual level display. Battery operated unit includes a low power indicator and automatically shuts off after three minutes of non-use. Includes 9V battery and instruction manual. Salinity range: 0 to 50 PSU/ 0 to 150 ppt/ 1.000 to 1.114 S.G. (20/20); resolution: 1 PSU/ 1 ppt/ 0.001 S.G. (20/20); accuracy: ±2 PSU/ ±2 ppt/ ±0.002 S.G. (20/20). Temperature range: 0°–80°C/ 32°–176°F; resolution: 0.1°C / 0.1°F; accuracy: ±0.3°C / ±0.5°F. Size: 192 x 102 x 67mm. Weight: 420 g.

Salinity Range: 0 - 50 PSU; 0 - 150ppt; 1.000 - 1.114 SG. Resolution: 1 PSU; 1ppt; 0.001 SG. Accuracy: ±2 PSU; ±2ppt; ±0.002 SG.
Temperature Range: 0 - 80°C/32 - 176°F. Resolution: 0.1°C/°F. Accuracy: ±0.3°C/0.5°F
