Introduction
1.1 Introduction
The Teledyne Analytical Instruments (TAI) Model 3110 Portable Trace Oxygen Analyzer is a portable, intrinsically safe oxygen analyzer capable of analyzing oxygen levels from 2 parts per million (ppm) oxygen.
The instrument operates from internal rechargeable batteries and is supplied with a universal AC charge adapter. Featuring quick disconnect fittings for sample connections and a rugged lightweight housing with handle, this versatile instrument can be brought to the sample site and set up for analysis quickly and easily. Because of the intrinsically safe design, once calibrated, the instrument can be employed even in hazardous environments without compromise. The Model 3110 incorporates a large standard feature list designed for versatile, accurate oxygen analysis for a wide range of applications. Figure 1-1 shows the standard Model 3110 Portable Trace Oxygen Analyzer.
The microprocessor based Model 3110 instrument provides user settable analysis ranges at the trace level. The range can be set from 0-2 ppm to 0-25% oxygen. In auto-ranging mode two ranges can be set and the analyzer move between these ranges as required. The adjustment resolution is 0.1 ppm for trace analysis.
Sample oxygen is displayed on a 2-line 20 character alphanumeric LCD display mounted on the front panel. Four buttons are used to interface with the instrument and access all of the analyzer features.
Sample gas is introduced and vented via a pair of quick-disconnect fittings that feature integral shutoff valves that automatically close when the mating male fitting is withdrawn. The fittings are an integral part of the measuring cell manifold.

downloaded using the instrument’s optional RS-232 interface.
•Display: A 2-line 20 character alphanumeric LCD
on the front panel displays data and operational information through various screens. The contrast is adjustable for various lighting conditions.
•Four-Button User Interface: Operation is performed using the
four front panel mounted buttons. These buttons are used to enter data, select items and move through operational screens that appear on the display.
•Universal AC Charge Adapter: The rechargeable batteries can
be recharged without removing them from the instrument. The charger operates over the range of 100-240 VAC.
•LEDs: Two front panel mounted LEDs are used
to indicate low battery condition and when the battery is recharging.
•Contrast Control: This feature allows the user to easily
adjust the contrast of the display for optimum viewing under different lighting conditions. The adjustment is made using a front panel control dial.
•Auto-ranging: The user is able to specify two analytical
ranges for analysis in the auto mode. The Model 3110 will automatically switch between these ranges depending on the oxygen level.
•Percent of Range Voltage Output: An optional 0-1 VDC
output is available that represents the percentage of the current analysis range.
•Real-time Clock: This feature allows the Model 3110 to date
and time stamp the data set recorded on the data logger. It uses a 24 hour clock.

•Quick Disconnect Fittings: Dual self-sealing quick disconnect
fittings are installed for making easy sample connections.
1.3 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 linear, but minute signal produced by the transducer from oxygen is amplified by a two-stage amplifier. The O2 sensor output signal is digitized and fed to the microprocessor. Additional signal conditioning and temperature compensation are handled electronically and appropriate signals are directed to the display and output ports.
1.4 Micro-Fuel Cell
The micro-fuel cell (U.S. Pat. Nos. 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 removed, properly disposed of, and replaced with a new cell. The life of the cell is warranted by TAI (see below).
The cell is specific for oxygen and is not sensitive to flow rate or reducing agents such as hydrocarbons, carbon monoxide, sulfur dioxide, etc. In the absence of oxygen, no current is produced; thus, no zeroing is required.
1.4.1 Cell Warranty
The Class B2-C, A2C, B2C-XL and Insta Trace micro-fuel cells can be used in the Model 3110 and are warranted for six (6) months from the date of shipment.
With regard to spare cells, service time starts when the cell is removed from its shipping package. You should stock only one spare cell per instrument at a time.
If a cell was working satisfactorily but ceases to function before the warranty period expires, the sensor will be replaced at no cost.

If you have a warranty claim, return the cell in question to the factory for evaluation. If it is determined that failure is due to faulty workmanship or material, the cell will be replaced at no cost to you.
WARNING: EVIDENCE OF DAMAGE DUE TO TAMPERING OR MISHANDLING WILL RENDER THE CELL WARRANTY NULL AND VOID.
The Model 3110 is designed to meet Factory Mutual standards for intrinsically safe for Class I, Division I, Groups A, B, C and D hazardous locations. (Approval pending at time of manual printing.)
This safety feature does not apply when the instrument is being charged with the 100240 VAC external charge adapter. The instrument should be removed from hazardous areas when the batteries are being charged.
Note: Do not use the analyzer when the battery charge is low.
1.5 Accuracy and Response
The Model 3110 provides monitoring accuracies of ±2% of full scale or ±1 ppm, whichever is greater, at constant temperature.
With a sample flow rate of 1 SCFH, a 90% response can be realized in 60 seconds. The response time on the 3110 is limited by the filter setting.
1.6 Signal Output
The standard 0-1 VDC output has a 100 ohm impedance and is suitable for driving external devices that have an input impedance of 10,000 Ω or more. The signal output is available from a port on the rear panel.
1.7 Compact Packaging
The instrument is housed in 6 1/8"× ½9" × 5 5/8" (156× |
241× |
143 mm) aluminum case that is equipped with a carrying handle and foot pads. Unlike analog instruments where uneven positioning may
