Our verdict

A handheld analog sugar meter that corrects for temperature on its own, for checking Brix in juice, drinks and food samples. The scale ends at the low end of the Brix range, so heavy syrups need a higher-range model.

Overview

Not a digital meter, this is an analog handheld refractometer that converts a sample's refractive index into percent sugar by weight. A spoon-shaped tip spreads the sample across the prism, and a metal body is built to resist heat and organic solvents.

Automatic temperature correction and a one-drop sample are the reasons to choose it, since readings do not depend on adjusting for the room. The analog scale takes some practice to read at the boundary line, and the range is limited to the lower end of Brix.

Who it's for

People who want a rugged, battery-free meter for culinary, beverage, education or water-testing work. A buyer who needs higher Brix readings, or an on-screen number, should pick a digital or wider-range unit.

Pros and cons

Pros
  • Temperature correction is automatic
  • Needs no battery or power source
  • Spoon tip makes sampling smooth
  • Includes protective storage case
Cons
  • Analog scale takes practice to read
  • Range stops at the low end

Performance notes

Light bends differently through a sugary liquid than through plain water, and the scale shows where the bend falls on the boundary line. Automatic temperature compensation corrects for the sample warming or cooling, which would otherwise shift the reading. Ambient light illuminates the scale, so the unit needs no power.
