Overview

A pen-shaped probe tip, dipped into the sample or touched to it after pressing START, is the working end of this digital refractometer. The result shows on the display, and the pen is washed off after use.

Speed and simplicity are the case for it: dip, press, read, rinse. A continuous mode covers a sample that changes. The accuracy figure, resolution and power source are missing from the listing.

Who it's for

Users who test sugar content often and want a quick pen-style meter that needs no setup between samples. Buyers who need published accuracy figures, or a specific model name, should confirm with the seller first.
