Analog and digital sensors
For measuring pH, ORP, conductivity, and oxygen in process applications, we offer a variety of analog and digital Memosens sensors that were developed and optimized in close collaboration with users. Knick sensors require little maintenance and provide highly precise measurements with a robust design and long-lasting materials for the chemical, pharmaceutical, and food industries, as well as in the areas of energy and the environment.
The digital measurement is performed using Memosens technology, which enables preventative diagnostics for sensor health and offers many advantages.
Memosens Sensors – The Advantages at a Glance
- Plug & measure – sensor replacement in a matter of seconds with pre-calibrated sensors
- Easy and safe plugging thanks to its bayonet coupling
- Contactless, digital data transmission
- All critical data are available in the sensor
- Longer sensor service life
- Error-free measurements even under the most adverse conditions
- Only one cable system for all sensors
- The measurements are not affected by excessive cable lengths
