Salinity Refractometer MASTER-S/Millα

Description Features Configuration Application

The Atago 2491 MASTER-S/Millα (alpha) is a handheld, portable, water-resistant refractometer with a salinity scale that measures in the 0 to 100% range in parts per million, has specific gravity (1.000 to 1.070 ATC) measurement, 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.
