BIDDING ON A LOT OF 4EA SENSOREX TX10 PH & ORP TRANSMITTER RECOVERED FROM A PANEL FROM A CLOSED WATER TESTING FACILITY.  I WAS TOD THIS WAS WORKING WHEN FACILITY CLOSED BUT I HAVE NO WAY OF TESTING.  THAT IS WHY THE PRICE IS THIS LOW.
I ALSO HAVE PARTS OF THE PANEL MOUNT COVERS AND THE TABS THAT MOUNT THEM TO THE PANEL.  MAY NOT BE ENOUGH PANEL MOUNTING PARTS FOR ALL 4.  WHAT YOU SEE IN THE PICTURES IS WHAT YOU GET IN ADDITION TO THE PANEL CLEAR COVERS AND OTHER MISC PANEL MOUNTING ITEMS
