UR62 – Refractometric analyzer Bx / nD
BRIEF INTRODUCTION
The UR62 digital refractometer is a probe designed for simple installation in-line or in a tank or vessel. It continuously measures concentration and displays and outputs the result in Brix or nD or % concentration with basic accuracy.The UR62 will signal to the process when concentration is outside of specifications or has reached its target end point by means of analogue 4-20 mA output.The probe is easily set up and configured through a PC or portable computing device using its built in RS485 interface. It can also be connected to the optional RC-24 touch screen operator display unit.The analyzer does not have any drift in the time so that it does not need any adjustment vs the laboratory: after the initial configuration during start up, the operators in the plant do not have to touch the system anymore.Due to the optical technology, the equipment is virtually no maintenance: the robust construction with 316 stainless steel and IP67 protection, allows the installation in any aggressive environment using various Maselli mounting adapters.
