Advanced Micro-Fuel Cell specifically designed for trace
analysis
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 concentration (0-1 VDC and
isolated 4–20 mA DC) and two for range identification.
1.4 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
3020T-F:
Includes flame arrestors for Groups C and D.
3020T-G:
Includes flame arrestors for Groups C and D, & -C
option.
