HYDROLAB Surveyor 4 & HYDROLAB Mini Sonde Set of 2 $750

This offering consists of two(2) HYDROLAB Surveyor 4 Water Quality Displays, two(2) HYDROLAB MiniSondes, two(2) Power Supplies for the Displays, one(1) Generic Power Supply, two(2) Manuals, various sets(at least 4) of cables and some tools.

As for condition, both of the Displays power up and the screen appears for several seconds and then goes blank.  I think this is the unit going into power saving mode because it needs new batteries.  The Displays use DR30 batteries.  Both power supplies work.  As can be seen in the photos, one cable lacks the locking screw and another looks to be hand wired–both are pictured. The Sondes are untested.
