Knick digital and analog sensors for measuring pH/ORP, conductivity or oxygen

Sensors

This documents introduces the Knick range of digital and analog sensors for measuring pH/ORP, conductivity or oxygen.

The Knick pH sensors have been developed and optimized in close cooperation with users for a wide range of applications. Special glasses, a large variety of junctions (open, PTFE, ceramic, platinum), special reference systems, analog or digital with Memosens – Knick has the right sensor for every application.

The conductivity of aqueous solutions covers a range of more than eight decades, starting with 0.055 μS/cm for ultrapure water and going as far as over 1,000 mS/cm for fully dissociated acids or bases. These very different requirements are fulfilled by special Knick sensors. Depending on the application, they come as two- or four-electrode sensors or toroidal sensors. All sensors are equipped with a temperature detector for automatic temperature compensation.

Oxygen sensors from Knick are characterized by a high level of process safety: robust design, durable materials and modular structure. The membrane of the amperometric sensors is steel-mesh-reinforced and PTFE-coated and can be replaced quickly and easily, as can the electrode system with its complete inner body. The product portfolio includes sensors for trace measurements and low-maintenance digital optical oxygen sensors.
