The PTR100-CPT Compact Inline Refractometer, marketed under the Prismatech brand, is designed using modern technology and high-quality components to measure, display, and control the concentration of transparent and non-transparent solutions.
The device is installed directly on pipelines or tanks and performs real-time measurement of both the refractive index and temperature of the solution—two key parameters that influence concentration. After performing complex calculations and a three-step calibration and compensation process, the system displays the solution concentration in Brix units (°Bx).
The PTR100-CPT features a 128×64-pixel LCD display with touch-sensitive keys, mounted directly on the sensor, allowing users to view real-time measurement results instantly.
In addition, measurement data can be transmitted via digital (RS485) or analog (0/4–20 mA) output ports to an external local controller (such as a PLC).
One of the unique features of the Prismatech Inline Refractometer is its automatic PID-based concentration control, eliminating the need for a separate local controller.
The set point and all controller parameters (including proportional, integral, and derivative coefficients) are fully adjustable by the user.
Digital in-line refractometers, or digital Brix meters, operate using an LED light source that illuminates the sample placed above a prism. The refracted light is then detected by a sensor, which calculates the angle of refraction.
Because refractive index measurements are temperature-dependent, the device automatically applies temperature compensation using precise algorithms and converts the results into refractive index or other relevant parameters.
Compared to similar instruments, digital refractometers offer advantages such as ease of use, automatic temperature correction, and adjustable measurement ranges. They are also available in compact portable refractoemter models.
Digital refractometers can be customized for specific applications to enhance performance, though doing so may reduce their overall range of use.
Digital in-line refractometers are widely used for monitoring continuous industrial processes, typically installed on tanks or pipeline systems.
They are durable, low-maintenance instruments designed to perform real-time concentration and Brix measurements, enabling precise control of products during raw, intermediate, and final production stages.
These devices are essential tools for quality control, particularly in cases where a fast and accurate response is required to optimize processes or regulate sensitive production stages, such as purification or product quality monitoring.
