Salinity Refractometer MASTER-S28α

The Atago 2481 MASTER-S28α (alpha) is a handheld, portable, water-resistant refractometer with a salinity scale that measures in the 0.0 to 20.0% range, has automatic temperature compensation (ATC), and is housed in an Ingress-Protection (IP)-65 rated Polybutylene terephthalate (PBT) plastic body. A salinity refractometer measures the refractive index of a solution in a sample, converts it to seawater concentration in units of percent by weight (% salinity, also known as degrees salinity), and displays the results. Handheld refractometers, sometimes known as salinity meters, or concentration meters are commonly used in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, and ecological industries, and for water-testing applications.

  • Handheld portable refractometer for salinity (0.0 to 28.0%) measurement of concentration of salt water used in rinsing seafood or salt in cooking
  • Automatic temperature compensation (ATC) for immediate, accurate calibration readings, regardless of ambient temperature
  • Ambient light illuminates the scale; no additional power source is required
  • Ridged outer shell with a telescope-shaped, streamlined design (20.3 x 3.2 x 3.4cm) for gripping, and a spoon-shaped tip for smooth sampling
  • Polybutylene terephthalate (PBT) plastic body for use with salty and acidic samples; Ingress-Protection (IP)-65 rated for protection against dust and water jets






Sodium chloride : 0.0 to 28.0g/100g

Minimum Scale





The units can be used for controlling the concentration of saltwater used in rinsing seafood or salinity in cooking. NEW material which is durable for salty and acid sample is adopted. It has an Automatic Temperature Compensation (ATC) model with water resistant properties (IP65).
