Knick ORP Sensors
Knick’s ORP sensors are available in different versions – analog or digital with Memosens technology – even with explosion protection.
Thanks to the different sensor lengths and multiple connection options, they can be adapted to different fittings. These fittings include retractable fittings such as SensoGate and Ceramat, inline fittings, flow-through fittings, and immersion fittings to satisfy a broad range of application requirements.

The digital pH/ORP sensor SE555X/1-AMSN has a special pH glass with high impedance for high-temperature applications and low alkali error as well as a platinum disk as ORP measuring element.
The sensor is CIP and SIP capable. The silver ion trap prevents contamination and blocking of the junction by silver sulfide in sulfide-containing media. The reference electrolyte is biocompatible. This makes the sensor predestined for applications in food and biotechnology, but it is also suitable for continuous and simultaneous measurement of pH and ORP in process chemistry or wastewater.
In addition, the Memosens technology offers all known advantages in terms of handling and sensor diagnostics.
Applications
Fermentation, food and beverages, aggressive media, extreme pH values, waste water
