Teflon Body / Saunders Body Process Refractometer

K-Patents Saunders Body PR-23-W and K-Patents Teflon Body PR-23-M Refractometers provide accurate means for measuring liquid concentrations in chemically aggressive solutions that corrode, foul or otherwise destroy metal parts as well as in ultra-pure fine chemical processes, where metal parts cannot be used.

Teflon Body / Saunders Body Process Refractometer
