1 

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).
