The RT-100 Prism 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.
The RT-100 Prism is a very robust, digital sensor and is capable of operating in contaminated fluid samples. It is important however to note that users should take all precautions to mitigate and filter suspended solids from the sample stream prior to the sensor to avoid tenacious deposit build-up on the sensor eye. In highly fouled applications, Pyxis recommends users conduct sensor eye cleaning on a regular basis per the manual guidelines. Pyxis Lab is also developing will be launching an automated sensor cleaning accessory for installation into the Tri-Clamp Flow Cell assembly as an optional accessory in the near future.
