There are hundreds of ideal applications for process refractometers within the chemical and petrochemical industries. Some process measurements are linear, and some are not. The Model 326 has the ability to linearize/shape, or reverse, any customer’s product characteristics. This allows the process refractometer to track and produce accurate concentration measurements of products with a non-linear refractive index curve. Multiple linearized calibration tables may be stored and selected, as required. If desired, the measurement units, calibration, and correction points can selectively be changed at will, via the user-friendly touch-screen or remote web browser interface. The 4-20 mA output signal is automatically calibrated to the selected measurement range.
