Dome Online Refractometer MSDR-SH20-C, Brix Accuracy ±0.1% (CAT#: STEM-AL-7024-ZJF)

The MSDR-SH20-C is a dome-series online refractometer intended for narrow-range, high-accuracy concentration measurement. The unit uses an all-stainless-steel outer housing for process installation. Its dome sensing geometry is designed to work with a dedicated flow cell. A self-cleaning function helps reduce deposits on the sensing area during liquid measurement. The flow-cell arrangement also helps limit the attachment of impurities and bubbles around the sensor surface. Brix, refractive index, and temperature are measured through the installed sensing section. Threaded, flange, and clamp connections are available for integration with process piping or vessels. Analog and RS485 outputs provide concentration and communication interfaces to external equipment. The combined dome geometry and cleaning arrangement is intended to improve measurement stability where fouling or bubbles may affect an optical sensor.
