The Teledyne Analytical Instruments Model 306WA Trace Oxygen
Analyzer is designed to detect trace concentrations of oxygen in process
streams. It utilizes Teledyne’s patented electrochemical sensor which re-
quires minimal maintenance and exhibits a 90% response in less than one
minute. Cell output is insensitive to flow rate changes within the operating
range of the analyzer’s flowmeter.
The Model 306WA features a welded stainless sampling system for
long-term, leak-free operation.
While the analyzer is offered in several configurations, they are virtually
identical with the exception of housing or options such as special meters. For
purposes of clarity, this manual will discuss the unit in general, since differ-
ences will be minor and will be obvious to the user.
1.1 1.1 1.1 1.1 1.1 Method of Operation Method of Operation Method of Operation Method of Operation Method of Operation
Gas from the process stream is fed through a sample line to the sample
inlet port of the analyzer. The sample is directed through the analyzer’s
sample system, where oxygen concentration is detected by the sensor. The
sensor generates an output signal which is read out on a suitable recorder or
meter.
The analyzer components include a throttle valve and flowmeter to
control sample flow, a humidifier to condition the sample, the measuring cell
and its associated circuitry, and a calibrator to adjust the sensitivity of the
analyzer to the desired measurement range.

For proper operation, the analyzer may require accessory equipment,
particularly in the area of sample conditioning. The need for additional
equipment is dictated by the conditions of each application.
