Developed by Systech Illinois’, our specialist gas and moisture inspection company, our oxygen analyzers offer unsurpassed accuracy, reliability and flexibility under the most demanding on-line operating conditions .
The accuracy of our ZR800 oxygen analyzers is relied upon by companies of all sizes across the electronics, semiconductor, food processing and gas manufacturing industries.
Our panel or bench-mounted oxygen analyzers are ultra fast. The response times you enjoy are unparalleled in the industry – the competition simply can’t keep up!
These microprocessor controlled instruments have user-friendly menu driven software. You can even customize our oxygen analyzers to meet your requirements.
Our robust and reliable oxygen detectors are IP66 waterproof and weatherproof, so you can rely on them in the most challenging of environments. Here’s just some of the applications our oxygen analyzers support:
All ZR800 oxygen analyzers feature precision zirconium dioxide oxygen sensors for high the most accurate oxygen detection available.
The oxygen detection cell is a high purity, high density, stabilized zirconia ceramic. The oxygen sensor produces a voltage signal relative to the oxygen concentration of the sample gas stream. The cell’s logarithmic output is converted and linearized by a high speed microprocessor, providing a direct digital readout on the instrument’s LED display.
We make a range of oxygen detection devices and accessories. For example, check out the EC92DIS ATEX portable oxygen analyzer or the 8700 & 8701 OxySense® Oxygen permeability analyser to start.
We like to share the knowledge we have amassed over the decades at Industrial Physics. Why not visit our blog on measuring gas with zirconia oxygen analyzers, or this one that covers electrochemical cells used in oxygen analyzers.
The oxygen analyzer’s conventional zirconium oxide cell consists of a zirconium oxide ceramic tube plated with porous platinum electrodes on its inner and outer surfaces. As the oxygen sensor is heated above 1112ºF, it becomes permeable to oxygen ions (O2) with vacancies in its crystal lattice structure permitting their mobility.
Because of this, the oxygen sensor becomes an oxygen ion conducting electrolyte. The electrodes provide a catalytic surface for the change in oxygen molecules, O2, to oxygen ions, and oxygen ions to oxygen molecules.
Oxygen molecules on the high concentration reference gas side of the oxygen analyzer’s cell gain electrons to become ions which enter the electrolyte. Simultaneously, at the inner electrode, oxygen ions lose electrons and become released from the surface as oxygen molecules.
When the oxygen concentration differs on each side of the sensor, oxygen ions migrate from the high concentration side to the low concentration side. This ion flow creates an electronic imbalance resulting in a DC voltage across the electrodes. This voltage is a function of the sensor temperature and the ratio of oxygen partial pressures (concentrations) on each side of the oxygen sensor.
