UR24 – In-line process refractometer

BRIX / nD / USER SCALE

DESCRIPTION

The UR24 digital refractometer is a stand-alone unit designed for simple installation in-line or in a tank. The analyzer provides a continuous measurement of concentration that can display the result in Brix, nD, or % concentration with high accuracy. The UR 24 also features a user programmable scale for specific applications. The analyzer provides an output signal that can be used for process control. The output signals can be configured as analog or digital. After initial installation and configuration no further measurement adjustments are required. The sensor measurement utilizes optical technology, so it is maintenance free. The sensor is incased in a stainless-steel structure and is IP67 rated. This robust construction allows the sensor to be mounted in any industrial environment utilizing a variety of Maselli mounting options.
