1. AUTOMATIC & WATER RESISTANT REFRACTOMETER
Atago 2491
FUNCTION:
• Handheld portable refractometer for salini-
ty (0 to 100%) and specific gravity (1.000 to
1.070 ATC) measurement of seawater used in
rinsing seafood or salt in cooking
• Automatic temperature compensation (ATC)
for immediate and accurate readings, regard-
less of ambient temperature
• Unit displays in parts per million (%)
• Ridged outer shell with a telescope-shaped,
streamlined design (20.7 x 3.2 x 3.4cm) for
gripping, and a spoon-shaped tip for smooth
sampling

body for use with salty and acidic samples; In-
gress-Protection (IP)-65 rated for protection
against dust and water jets

PRODUCT DESCRIPTION:
The Atago 2491 MASTER-S/Millα (alpha) is a handheld, portable, water-resistant refractometer with a salinity scale that meas-
ures 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, edu-
cational, geological, chemical, and ecological industries, and for water-testing applications.
