I need a refractometer to check Glycerin, and possibly propylene glycol. What handheld palm abbe would be best for me? The PA202 or PA203 Will the PA202 measure glycol? Does the pa203 come with pre-installed scales or custom scales for each use? My application is for antifreeze. Fahrenheit readings please. Please advise.
With the right combination of scales, either the Palm Abbe PA202x or PA203 digital refractometer will handle the job of measuring glycerin and propylene glycol antifreeze solutions. Scales are available to read nearly any physical property of glycerin and propylene glycol, including scales for freeze point and concentration or other units of measure such as specific gravity, density, percent by weight or volume, and more.
