High measuring precision in a compact design

The SensoRef sensor from Schmidt + Haensch opens up a new field of miniaturization for process refractometers.

Thanks to the new optical design, the actual sensor has the size of a golf ball. It design requires fewer parts, resulting in a highly efficient and compact construction. As a true sensor, it can be used in applications which can not be met by conventional refractometers.

If you are dealing with minimal volumes, space-limited installations or mobile operation, Schmidt + Haensch has another ultimate solution for you here.

Designed to be easily integrated into your process controls, it can be connected directly to your PLC via Modbus or RS-232 interface. Integrated functions such as temperature measurement, cleanliness control and filling level detection ensure a self-monitoring system.
