Teledyne Analytical Instruments
Models 3190 and 3290
Outputs For Data
A standard 0-10 VDC output provides range identification,
while the oxygen concentration is output through 4-20 mADC
negative ground and 0-10 VDC negative ground signals. An
optional unidirectional RS-232 serial interface is in­cor­porated to
relay information to a host computer for remote monitoring of all
functions. Configuration information and analysis results are as
close as your personal computer.
Advantages

Trace & Percent Oxygen Analyzers
Fuel Cell or Zirconium Oxide Sensors
Good things come in small packages, and Teledyne’s 3190
Trace or 3290 Percent Oxygen Analyzer proves it. These
microprocessor based units offer high accuracy, easy use,
and all the standard features demanded by the end-user in a
compact, budget priced design.
Membrane command switches and a large, four digit LED
display make setup and operation clear and quick. For the
latest technology, Teledyne quality, and an unbeatable value,
the 3190 or 3290 provides a pocket-sized solution.
Field-Configurable Range Options
Depending on the application, these units can be configured
to utilize one of Teledyne’s patented, Micro-fuel Cell sensors
or zirconium oxide sensors, assuring the highest accuracy.
With a long expected sensor life, the 3190 or 3290 is as
inexpensive to maintain as it is to purchase.Teledyne has
even provided a sensor failure alarm, taking the worry and
work out of the end-user’s hands.
Two ranges are field configurable on Model 3190 at 0-10 ppm
and 0-1000 ppm with a 0-25% calibration range. Optional
ranges can be set between 10 ppm and 10,000 ppm.
The 3290 ranges are field configurable between 1% and 25%
oxygen with 0-25% oxygen calibration. An optional full scale
range is available up to 100%. Autoranging is standard on
both models.
