Recently purchased this simple device to measure sugar content or BRIX of my various juices. It has a scale of from 0 to 32 brix and at first look appears to be a quality product.This refractometer from SainSonic is easy to calibrate and simple to use for testing Brix values in food and gardening applications.Reasonably priced and comes with a compact protective case for storage.
