Limiting Current Type Oxygen Analyzer OX102

 

The OX102 Oxygen Analyzer measures oxygen concentration from ppm to percent levels in a single analyzer and is ideal for ppm-level measurements in applications such as nitrogen reflow furnaces and semiconductor plants.

 

The zirconia oxygen sensor uses a method that is based on the limiting current principle and is compact, yet has high-performance. The sensor is designed for installation by direct insertion

 

When a sample gas contains organic solvent at a few ppm to percent level in applications such as nitrogen reflow furnaces, an optional sampling unit is required.

 

One instrument capable of measuring from 0 - 100 ppm to 0 - 25% oxygen

Simple one touch calibration

Self diagnostics assure high reliability

One touch sensor replacement

Compact size

 

Measuring Principle

 

Current flowing in the Zirconia fixed electrolyte causes oxygen to move from the negative to positive electrode (acts as an oxygen pump). If the flow of oxygen to the negative electrode is restricted by the alumina substrate then a current saturation area is created and the same current flows regardless of the applied voltage. The current that flows is called the limiting current. When a fixed voltage is applied, the current flow is proportional to the oxygen concentration.

Applications

 

N2 reflow furnaces

Semiconductor maker environmental monitoring

ppm-level O2 measurement

Monitoring purity of N2, Ar separated from air

Monitoring for deficiency of O2
