1. A tester for a steam or hot water component having at least one device, comprising:
a probe extending between a distal end and a proximal end;
the distal end of the probe defining a probe tip to contact the at least one device;
a first acoustic element located adjacent to the proximal end of the probe tip;
a second acoustic element spaced apart from the first acoustic element such that there is a space between the first acoustic element and the second acoustic element;
an electrode located between and spacing the first acoustic element and the second acoustic element;
a stud extending internally through the first acoustic element and the second acoustic element and at a distal end into the electrode;
a stack mass adjacent to the second acoustic element and remote from the first acoustic element; and
a head located on the stud proximate the stack mass and electrically connected to the electrode to detect acoustic readings at the probe tip.
