The Pyxis RT-100 PRISM Inline Refractometer is an inline digital refractometer that measures the refractive index of a liquid sample and provides a direct reading of highly accurate concentration values for a wide variety of water and process related applications. It is a stand-alone device capable of self-sustained operation, live data display and data logging.

The RT-100 Prism also offers fully integrated 4-20mA and RS-485 Modbus output signals for connectivity to any microprocessor-based controller, display, PLC or DCS network. The RT-100 Prism has built-in temperature dependent equations to convert the measured sample temperature and refractive index to the percentage concentration of Mono-Ethylene Glycol (MEG), Mono-Propylene Glycol (MPG), Sugar Content (Brix) and Advanced Low Viscosity Fluid (ALV). Additional concentration curves may be added in the future by Pyxis Lab as the market demands.
