1 Introduction
Model 3020T
Teledyne Analytical Instruments
•
Advanced Micro-Fuel Cell, redesigned for trace analysis, has an
expected life of one year.
•
Versatile analysis over a wide range of applications.
•
Microprocessor based electronics: 8-bit CMOS microprocessor
with 32 kB RAM and 128 kB ROM.
•
Three user definable output ranges (from 0-10 ppm through 0-
250,000 ppm) allow best match to users process and equipment.
•
Air-calibration range for convenient spanning at 20.9 %.
•
Auto Ranging allows analyzer to automatically select the proper
preset range for a given measurement. Manual override allows
the user to lock onto a specific range of interest.
•
Two adjustable concentration alarms and a system failure alarm.
•
Extensive self-diagnostic testing, at startup and on demand, with
continuous power-supply monitoring.
•
RS-232 serial digital port for use with a computer or other digital
communication device.
•
Four analog outputs: two for measurement (0–1 V dc and
Isolated 4–20 mA dc) and two for range identification.

Model Designations
3020T:
Standard model.
3020T-C:
In addition to all standard features, this model also has
separate ports for zero and span gases, and built-in control
valves. The internal valves are entirely under the control of
the 3020T electronics, to automatically switch between gases
in synchronization with the analyzer’s operations

Flame arrestors for Groups C and D installed.
3020T-G:
Flame arrestors for Groups C and D, & -C option, installed.
3020T-H:
Flame arrestors for Group B (hydrogen) installed.
3020T-I:
Flame arrestors for Group B, & -C option, installed.
All of the above options are available in combination.
