Teledyne Analytical Instruments
• 316 Stainless steel cell block and sample system—all wetted
parts.
• Advanced Micro-Fuel Cell for trace analysis. Standard
Insta Trace cell
has rapid recovery from air to low ppm during initial installation.
•
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 0-1 ppm through 0-
25 % 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.
• Analog outputs for concentration and range identification.
(0-1 V dc standard, and isolated 4–20 mA dc optional.)
1.4 Model Designations
3000TB
­XL: Standard model.
3000TB
­XL-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 3000TB­XL electronics, to automatically switch between
gases in synchronization with the analyzer’s operations.
