*The microprocessor-based flow controller within the 1425A produces accurate flow rates from
1.7 to 12.5 ml/sec with better than 1.5% Full Scale Accuracy. However, the accuracy of the
1425A system as a whole is based on a number of factors, including (but not limited to) tem-
perature, flow setting, ultrasound settings, etc. The accuracy of the complete 1425A system
may vary. For more information, see pages 19-21, Accurracy of Flow Velocity Readout.
If equipment is used in a manner not specified by Gammex,
the protection provided by this equipment may be impaired.
