PAROX 1200

The Parox 1200 paramagnetic oxygen sensor module is designed for incorporation in your analyzer-systems or for the solution of oxygen measuring problems using a microprocessor or PLC-system. The modules are maintenance-free, have a long lifetime, give a rapid and accurate signal response and are virtually insensitive to other gases.

Measuring principle

Paramagnetic (partial pressure measuring with a rotatable glass dumbbell). The sensor is available as a heated or non-heated model.
