> Handheld Refractometers

Our handheld refractometers can be broadly divided into two categories: analog and digital. 

Digital Refractometers

Our digital hand-held refractometers offer a convinient way to measure samples. No more guessing where the boundary line is - these units give readings as numbers. This also eliminates subjectivity and individual differences. Going digital also saves time and effort. 

PAL Series

The PAL series is the original pocket refractometer. 

PR Series

Pallette style units that offer accuracy and convinience. 

PEN Series

Pen-style handheld refractometers that you can dip directly into your samples for the ultimate in convience. 

QR Series

Suction-type refractometers for volatile or potentially hazardous samples. Includes models specifically for sodium hydroxide and sulfuric acid. 

Analog Refractometers

Analog provides a simple and afforadable way to measure samples. No fuss and no batteries to worry about. 


ATAGO's MASTER series represents the ultimate in hand-held refractometer function, operation, and design. Simple to operate and easy to take care of, the MASTER series will have you feeling like, well, a master.
