Seawater (Salinity)

Atago Seawater, Ocean Water, Sea Water, Artificial Seawater Salts/Salinity Refractometers

These refractometers are generally used in aquatic fields, educational studies, etc. to measure the total concentration/salinity of salts in seawater. Salinity values are typically displayed in ppt (parts per thousand) or specific gravity.

2491 MASTER-S/Mill-a

Atago 2491 MASTER-S/Mill-a (alpha) Handheld Seawater Salinity Refractometer.
Seawater Salinity: 0 - 100‰ ppt ± 1 (minimum scale 1‰ ppt)
Seawater Specific Gravity: 1.000 - 1.070 ± 0.001 (minimum scale 0.001)
ATC: Automatic Temperature Compensation: 50-86°F (10-30°C).
IP65: Dust-tight and protected against water jets (safe to clean up under the faucet).
The MASTER-S/Mill-a (alpha) is used to measures the salinity and specific gravity of seawater, and utilizes a new material that is durable against salty samples, The salinity of seawater is displayed in parts per mill (‰).
Replaces the discontinued model 2444 ATC-S/Mill-E.
Includes: Protective storage case and owner's manual.
