What People Are Saying
"Anyone who brews beer should find this product one of the best investments they make on any piece of equipment."
"I am in love with this instrument. No more large samples. No more phony readings from badly made refractometers."
"Dramatically improved my commercial brewing consistency & efficiency. Now I can quickly stop my sparge when I get to my OG."
"I used this for finishing Maple Syrup. I had been trying to determine sugar content using temperature and a hydrometer. I found both very difficult to use. The refractometer was much easier."
