The Teledyne Electronic Technologies/Analytical Instruments (TET/AI)
Series 320BRC and 320P Portable Oxygen Detectors meet or exceed all of
the requirements of the Commonwealth of Europe (CE) for Radio Fre-
quency Interference and Electromagnetic Interference (RFI/EMI) protec-
tion. Models 320A and 320B are
not complying with the requirements of
the Commonwealth of Europe. The analyzers are designed to continuously
measure the percentage of oxygen in a gas atmosphere. The measurement
is specific for oxygen and no special standardization or zero gases are
required. A letter designation, after the model number, indicates a specific
version as specified by the customer at time of purchase.
The 320A requires 115VAC or 220VAC 50/60Hz
The 320B uses four replaceable D-size batteries.
The 320BRC is powered by two permanently mounted recharge-
able nickel-cadmium batteries.
The 320P is powered by two permanently mounted rechargeable
nickel-cadmium batteries and has an integral sample pump. This
analyzer is designed to make spot check measurements of oxygen
in flue gas and process gas streams.
Oxygen is sensed using a TET/AI patented micro-fuel cell (MFC), that
consumes oxygen from the atmosphere surrounding the measuring probe
and generates a proportional electric current. The generated current is
amplified and read out on a built-in meter. A voltage output is available for
driving an external recorder. A selective range attenuation circuit and a
temperature compensation circuit provide temperature compensated out-
puts.
The standard operating ranges for Models 320A, 320B and BRC are 0-5%,
0-25% and 0-100% oxygen. The standard operating ranges for the Model
320P are 0-5%, 0-10% and 0-25% oxygen.
