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.
