Introduction

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.

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).
