Abstract
Abstract A casing having rounded corners for ease of insertion into narrow confines defines a protective chamber and has openings permitting fluids exterior to the casing to enter the chamber. There is a fluid monitor within the chamber having a surface adapted for exposure to the fluids. There is a compartment within the casing insulated from the fluids and containing a second fluid monitor. A stainless steel cable is attached to the casing for inserting the probe between the walls of a double-walled tank. In an alternative embodiment there is a channel within the casing for receiving the distal end of an electrician's fish.
