Important Notice
This instrument is intended to be used as a tool to gather valuable data. The
information provided by the instrument may assist the user in eliminating potential
hazards caused by the process that the instrument is intended to monitor; however, it is
essential that all personnel involved in the use of the instrument or its interface with
the process being measured be properly trained in the process itself, as well as all
instrumentation related to it.
The safety of personnel is ultimately the responsibility of those who control process
conditions. While this instrument may be able to provide early warning of imminent
danger, it has no control over process conditions, and can be misused. In particular, any
alarm or control system installed must be tested and understood, both as to how they
operate and as to how they can be defeated. Any safeguards required such as locks, labels,
or redundancy must be provided by the user or specifically requested of Teledyne when
the order is placed.
The purchaser must be aware of the hazardous conditions inherent in the process(es)
he uses. He is responsible for training his personnel, for providing hazard warning
methods and instrumentation per the appropriate standards, and for ensuring that hazard
warning devices and instrumentation are maintained and operated properly.
Teledyne Analytical Instruments (TAI), the manufacturer of this instrument, cannot
accept responsibility for conditions beyond its knowledge and control. No statement
expressed or implied by this document or any information disseminated by the
manufacturer or his agents is to be construed as a warranty of adequate safety control
under the user’s process conditions.

Portable Trace Oxygen Analyzer TURBO
Introduction
The Teledyne Analytical Instruments Model TURBO2 is a portable
trace oxygen analyzer which does not need an external power source to
operate, and can be reliably calibrated without the use of additional calibration gases.
The instrument provides for trace oxygen analysis in measuring ranges
of 0-100, 0-1,000 and 0-10,000 PPM (full scale), plus a special calibration
range that encompasses the known oxygen concentration of atmospheric air
(209,000 PPM).
2
Sample oxygen is read from an extremely accurate integral meter (0.5%
linearity) whose range of measurement is determined by the position of the
range selector switch. The 100-division meter scale and the multiplying
factor indicated by the position of the range switch determine the full scale
oxygen sensitivity of the instrument.
Sample gas is introduced and vented via a pair of quick disconnect
fittings that feature integral shutoff valves which automatically close when
the mating male fitting is withdrawn. The fittings are an integral part of the
measuring cell manifold so that internal sample passage volume is at an
absolute minimum. Sample flow control, although not critical (0.1 to 10
liters/min.), is either accomplished with accessory equipment or by the
addition of a pump and flowmeter (TURBO
2
P).
Method of Analysis
The sample oxygen is measured by a unique electrochemical transducer
which functions as a fuel cell; in this instance, the fuel is oxygen. Oxygen
diffusing into the cell reacts chemically to produce an electrical current that is
proportional to the oxygen concentration in the gas phase immediately
adjacent to the transducer’s sensing surface. The Micro-fuel Cell is a Class
S-2, designed for a quick recovery time from air to low PPM levels of
oxygen.

The linear, but minute, signal produced by the transducer from trace
oxygen is amplified by a two stage amplifier. The dual stages of amplification provide enough gain to drive the 0-100 microampere meter and thermistor controlled network utilized to compensate for the positive temperature
coefficient of the transducer.
Features
Micro-Fuel Cell:The Micro-fuel Cell (U.S. Pat. #s 3,767,552 and
3,668,101) is a sealed electrochemical transducer with no electrolyte to
change or electrodes to clean. When the cell reaches the end of its useful life,
it is merely thrown away and replaced, as one would replace a worn-out
flashlight battery. The life of the cell is warranted by TAI (see Cell Warranty, page 11).
Reliable Calibration: The unique qualities of the Micro-fuel Cell
allows the user to calibrate the instrument with the most economical, reliable,
abundant, standardization gas there is—atmospheric air.
The special CAL range of the instrument features a mark that coincides
with the 209,000 PPM oxygen concentration of air. By drawing air through
the instrument (see Calibration, page 6) reliable calibration can be achieved.
After the electronics have been properly zeroed (a one-time factory
operation), the instrument cannot produce an output indication in the absence
of oxygen; therefore, there is no need for a zero standardization gas.
Integral Power Supply: For pump option 4, the differential power
requirement (+ and – 3.6 VDC) of the instrument amplifier is furnished by
two internally mounted 750 milliampere•hour NiCad batteries. Fully
charged, these batteries will provide enough power to operate the instrument
continuously for a period of about 45 days with the pump option OFF. With
the pump option ON, the batteries will provide continuous operation for
about 8 hours. With the pump option OFF, an overnight charge of 14–16
hours on a one-month duty cycle should keep the original batteries supplied
usable for many years. With the pump option ON, charge 14–16 hours on
an 8-hour duty cycle.
An integral charging circuit and a detachable power cord are provided
so that the batteries may be recharged from any 50 or 60 cycle, 105 to 125
volt (90 to 110 volt optional), outlet.

Portable Trace Oxygen Analyzer TURBO
The instrument is designed to either sample or have its batteries recharged. Both operations cannot be carried out simultaneously. TAI has
deliberately interlocked the circuitry so that both operations cannot be carried
out at the same time.
Only when the selector switch is placed in the OFF position will the
neon lamp on the back plate of the Model TURBO
light up to indicate
2
power to the battery charging circuit.
To determine the state of the rechargeable batteries, turn the Range
Selector Switch counterclockwise to the battery test position and hold there
(the switch is spring loaded). Watch the meter indicator: if it does not stay
within the battery limits, the batteries need to be recharged. Release the
Range Selector Switch and it will automatically return to the OFF position.

Accuracy and Response: The Model TURBO
provides monitoring
2
accuracies of ±2% of full scale or ±5 PPM, whichever is greater, at constant
temperature. A ±5% of reading accuracy is achievable throughout the operating temperature range of 30 to 125° F.
With a sample flowrate of 150 cc/min., 90% response is achieved in 5–
10 seconds in the 0–10, 0–100, 0–1000, and CAL range switch positions.
Compact Packaging: The instrument is housed in 10¹/
16 " W × 7½ "
H × 6¾ " D aluminum case that is equipped with a carrying handle and foot
pads. When in use, the analyzer should be placed in an upright position on a
level surface (off-level positioning will detract from meter accuracy).
See Fig.1.
The cell block and amplifier PC board are housed inside the analyzer.
The back panel of the analyzer contains the AC power receptacle, the amber
charge light, fuse (½A: 110V; ¼A: 220V), and quick-connect fittings for
bringing the sample into and out of the sensor assembly.
Pump: The TURBO
P has an integral pump used to help draw
