This warranty does not cover defects caused by wear, accident, misuse, neglect or repairs other than those performed by TI/AI or an authorized service center. We assume no liability for direct or indirect damages of any kind and the purchaser by the acceptance of the equipment will assume all liability for any damage which may result from its use or misuse.
We reserve the right to employ any suitable material in the manufacture of our apparatus, and to make any alterations in the dimensions, shape or weight of any parts, in so far as such alterations do not adversely affect our warranty.
Important Notice
This instrument provides measurement readings to its use r, an d serves as a tool b y whic h valuable data can be gathered. The information provided by the instrument may assist the user in eliminating potential hazards caused by his process; 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 it can be misused. In particular, any alarm or control systems 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 TI/AI at the time the order is placed.
Therefore, the purchaser must be aware of the hazardous process conditions. The purchaser is responsible for the training of 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 Instruments/ Analytical Instruments, 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 its agents, is to be construed as a warranty of adequate safety control under the user’s process conditions.

Trace Oxygen Analyzer Introduction
Introduction
1.1 Overview
The Teledyne Analytical Instruments (TAI) Model 3300ZB is a microprocessor-based trace oxygen analyzer for real-time measurement of trace amounts of oxygen in inert gases, or in a wide variety of gas mixtures. It features simple operation, fast response, and a compact, rugged construction.
1.2 Main Features of the Analyzer
The main features of the analyzer include:
High resolution, accurate readings of oxygen content from 0-10
parts per million (ppm) through 0-1,000 ppm. Large, bright, light-emitting-diode meter readout
Simple pushbutton controls Advanced zirconium oxide measuring technology sensors Fast response and recovery time Microprocessor based electronics: 8-bit CMOS with on-board
RAM and 16 KB ROM
Two user selectable ranges (depending on sensor configuration)
allow best match to user’s process and equipment
Operator can select auto-ranging, allowing the analyzer to
automatically select the proper preset range for a given measurement or lock the analyzer onto a single range
Two concentration alarms with adjustable set-points Three analog outputs: two for measurement (0–10 VDC and
negative ground 4–20 mADC) and one for range identification (0-10 VDC).
