INSTALLATION CALIBRATION Delivery consists of three parts: Sensor, Indicating transmitter and interconnecting cable. The cable is ready for connection. The sensor is mounted in the process by a piece of standard pipe and a standard flance or clamp. A nozzle for prism wash with steam or hot wateris recommended in some applications. To obtain full agreement between refractometer indication and user´s laboratory determinations, the instrument may need adjustement. The user can make the adjustement himself using conventional methods, but he can also use the adjustment service provided by K-Patents:...

PRINCIPLE OF MEASUREMENT Light source Prism Reflected light Cr Solution itic a al ng le Refracted light When a light ray meets a surface wetted by a solution at a steep angle, part of the light is reflected, part is refracted. Total reflection The angel corresponding to the shadow edge in the optical image is called the Critical Angle of Total Reflection. THE CRITICAL ANGLE OF TOTAL REFLECTION IS A FUNCTION OF THE CONCENTRATION OF THE SOLUTION. Low concentration However, if the angle is flat, all light is reflected; total reflection occurs. High concentration If the position of the shadow edge...
