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.

PAROX 2000 19" oxygen analyzer
All analyzers are based on the paramagnetic oxygen sensor PAROX 1000 or 1100 with a rotable glass dumbbell.
The PAROX 2000 are precise oxygen gauges for continuous monitoring purposes.
The instruments are microprocessor controlled with self diagnosis capability.
PAROX 2100 oxygen analyzer
The operation and parameterisation is carried out by means of 4 keys and a 16-digit LCD display.
Options: pressure compensation, test gas pump, through flow alarm unit, NDIR sensors for CO
