I have for sale 1 used Extech RF15 Refractometer. This has the automatic temperature compensation and reads from 0-32 Brix. I had only used this a few times and is in perfect condition. This comes with the protective case, adjustment screwdriver, bottle of calibration solution, and a pipette.
These sell for around $100 dollars new so I'm asking for $65 dollars shipped to anywhere in the USA VIA UPS Ground.
