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.

Low-Maintenance pH/ORP Sensor for Simultaneous Measurement in Demanding Chemical Industry Processes
- Simultaneous measurement of pH and ORP value possible
- Solid electrolyte
- Integrated temperature detector
- Low maintenance, no electrolyte refilling
- 2 open hole junctions, no blockage due to solids in the medium
- Perfect galvanic isolation thanks to Memosens technology
- No influence of humidity in the connector
- Precalibration in the lab
- Digital data transfer
The special design allows for high accuracy, stability and durability. The reference system is in direct contact with the measured medium via two open connections, which minimizes the risk of a junction becoming blocked when there are solids in the medium. The high potassium chloride content and its distribution in the solid electrolyte reduce interference from diffusion potentials at the junction. The sensor with the advanced Memosens II technology by Knick is designed for higher ambient temperatures.
Memosens II by Knick:
- Ambient temperature up to 100 °C
- Ex approval for gas and dust
- Diagnostics with load matrix and statistics on transmitters with graphical display
Applications
Measurement in media of extremely high ionic strength, salt brines, strongly oxidizing media, acidic and alkaline media
