1.4 Model Designations
3000ZA: Standard model for sample under pressure
3000ZA-C: In addition to all the 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 3000ZA electronics to automatically
switch between gases in synchronization
with the analyxer’s operation.
