Applications

The nondepleting oxygen cell is an electrochemical
oxygen sensor used for oxygen measurement in the
following industries and applications:

Metals Industry

•O2atmospheres in heat-treating furnaces

Semiconductor Industry

• Gas purity/trace O

2

Gas Production Industry

• Purity monitoring of argon, hydrogen, nitrogen and
helium

Petrochemical Industry

• Purity of olefins

Features

• Used with Moisture Series analyzers to measure
oxygen concentration in gases from trace to percent
levels

• Ultralow range for ultrapure gas applications is
sensitive to less than 5 ppb oxygen

• Sensors available for indoor/outdoor water- and
dust-tight enclosures

• No gas scrubbing equipment needed for acid gas
applications

• No periodic replacement or reconditioning of cells is
needed

• Explosion-proof sensors available for hazardous areas

• VCR fittings assure system cleanliness and integrity

Nondepleting Oxygen Cell with
Electrolytic Oxygen Sensor

Periodic Replacement and Reconditioning Eliminated

The sensor operates on a simple coulometric process in
which oxygen in the sample gas is reduced in an
electrochemical cell. Unlike conventional electrochemical
oxygen cells, the electrodes in this advanced cell are
nondepleting, so they don’t undergo chemical changes
as oxygen is measured. As a result, periodic cell
replacement or conditioning is not required.

Parts Per Billion Oxygen Measurement

For oxygen measurement in ultrapure gas applications,
an ultralow range sensor that is sensitive to less than
five ppb is available. The sensor is equipped with VCR
fittings to ensure system cleanliness and integrity.

Withstands Acid Gases

For most applications where acid gas constituents are
present, the patented STAB-EL™ electrolyte option
eliminates the need for troublesome gas scrubbing
equipment by permitting direct exposure of the cell to
the gas stream. These cells have a reputation for
reliability in applications that are too difficult for most
other oxygen sensors.

Sensor Placement

The basic sensor is available separately. However, for
Type 4 applications requiring indoor/outdoor water- and
dust-tight enclosures, an R4 sensor is available that is
housed in a weatherproof enclosure with integral
mounting flanges. For hazardous (classified) locations,
an R7 sensor is available. It is housed in an
explosion-proof, aluminum electrical box that is rated for
hydrogen service, and can be used in Class I,
Groups B,C&D; Class II, Groups E,F&G; and Class III,
hazardous locations.
