public class EpicsEurotherm903
extends ScannableBase

This class controls a Eurotherm903 furnace using the EPICS interface. It was originally written for use with the B18 Eurotherm (in a B18 specific plugin). This is a cleaned up version of that class developed when using the same furnace on I20, with 'moveAndWait' function added, and moved to a non beamline specific package. TODO: Use this class on B18 and use new 'moveAndWait' method to replace equivalent functionality currently in B18SampleEnvironmentIterator; implement this class by extending TemperatureBase
