Introduction
1.1 Overview
The Teledyne Electronic Technologies Analytical Instruments
(TETAI) Model 3190Z 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).
