1 Introduction Model Ultra Trace 3000
Teledyne Analytical Instruments
•Advanced Micro-Fuel Cell, designed for trace analysis, has a 0-
250 ppb low range with less than a 100 ppb offset and six
months warranty and an expected lifetime 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 0-250 ppb through 0-
1000 ppm) allow best match to users process and equipment, plus
a fixed 1000 ppm over range.
•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.
•Two way RFI protection.
•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.
•Convenient and versatile, steel, flush-panel or rack-mountable
case with slide-out electronics drawer.
