Digital Refractometer for Invert Sugar
The Milwaukee digital invert sugar refractometer is temperature compensated with a 0 to 85% MASS range and +/- 0.2 percent accuracy. It is easy to use with a simple two-button operation and fast with a response time under 2 seconds. Within seconds the instrument measures the refractive index of the sample and converts it to % by weight concentration units. Maintenance is a breeze also with an easy-to-clean sealed flint glass prism and stainless steel well.
Thousands of food and beverage professionals and hobbyists, from chefs and food quality professionals and beverage manufacturers, have moved to digital invert sugar measurement from less accurate and less precise optical refractometers for sugar analysis.
Design Features
- Fast, accurate results with digital dual-level LCD readout
- Easy measurement with just 2-3 drops of sample needed and results in less than 2 seconds
- Simple 1 point calibration using distilled or deionized water
- Easy to clean, stainless steel sample well with a unit rated to IP65 as “dust tight” and protected against water jets
- Battery percent level indicator with automatic shut-off (batteries included)
- Ideal for beverage producers, fruit and vegetable growers, syrup producers, and food producers
- The measurement technique and temperature compensation employ methodology recommended in the ICUMSA Methods Book (Internationally recognized body for Sugar Analysis)
- Low Power Warnings
