Overview

Reading Brix through a focusable eyepiece, this handheld refractometer turns a small sample into percent sugar by weight. A spoon-shaped tip spreads the drop, and calibration against water is adjusted with an exposed screw.

Water resistance and a calibration routine that anyone can follow are the reasons to look at it. Temperature compensation is manual, which means more steps than the automatic version, and the scale covers a limited range.

Who it's for

Students, brewers and food testers who want a simple instrument without power and are comfortable setting temperature compensation themselves. Users measuring very sweet liquids should check the range first.

Pros and cons

Pros
  • Calibrates with plain water
  • No battery needed
  • Smooth sampling through the spoon tip
  • Protective case included
Cons
  • Temperature compensation is manual
  • Range limited to low Brix
  • Analog reading needs practice

Performance notes

Sugar in the sample bends light, and the boundary line against the analog scale gives the Brix value. Because compensation is manual, the temperature of the sample and the instrument has to be accounted for to hold accuracy. Calibration uses water, set by turning the exposed screw with the supplied screwdriver.

Frequently asked questions

Can the Atago MASTER-20M measure salt or alcohol?

The listing describes a Brix scale for sugar concentration, from 0.0 to 20.0 percent. No salinity or alcohol scale is described.

How is the Atago 2383 calibrated?

It can be calibrated with water using an exposed calibration screw and the included specialized screwdriver.

What does ASD mean on the Atago 2383?

Automatic sample distribution. The spoon-shaped tip spreads the sample across the prism, so the daylight plate does not need to be lifted.

Does the Atago 2383 need power?

No. Ambient light illuminates the scale and the unit requires no additional power source.
