Abstract

A conductivity testing device includes a body containing a magnet positioned to magnetically attach a mounting surface of the body to a surface to be tested. A testing chamber has an opening substantially in a plane with the mounting surface and valves positioned to allow the introducion of a fixed volume of liquid into the chamber. The chamber is sealed to the surface by a tubular resilint seal. An agitating device is mounted in the chamber for agitating liquid introduced into the chamber to wash the enclosed surface area. A testing circuit includes probes positioned in the chamber and a meter for indicating conductivity of a solution contained within the chamber. The testing circuit is electrically coupled to the agitating device in a first mode and connected to the probes in a second mode for testing conductivity of a solution in the chamber.
