Spacer and housing apparatus

A housing apparatus, comprising:

• a base portion having a top portion and a bottom portion that extends outward to an outer edge, two-pairs of opposed side portions extend upwardly from the outer edge to an upper edge forming a cavity therein, a top portion engages the upper edge and enclosing the cavity;
• a bore centrally located within the top portion and extending from a first side to a second side;
• a lip circumferentially surrounding the bore with a top surface;
• an elongate hollow sleeve surrounding the bore having a first end and a second end, wherein the first end is engaged to the lip and extending upwardly from the lip to the second end containing an upper edge, the elongate hollow sleeve is generally circular with an exterior surface and an interior surface;
• and
• a gasket is disposed on the top surface of the lip.

A spacer apparatus for engaging an ion measuring device, comprising:

• a base portion having a top portion and a bottom portion that extend outward to an outer edge, two-pairs of opposed side portions extend upwardly from the outer edge to an upper edge, forming a cavity therein;
• a bore centrally located within the base portion and extending from the top portion to the bottom portion;
• a lip circumferentially surrounding the bore extending upwardly from the top portion of the base portion containing a top surface;
• an elongate hollow sleeve surrounding the bore having a first end and a second end, wherein the first end is engaged to the lip and extending upwardly from the lip to the second end containing an upper edge, the elongate hollow sleeve is generally circular with an exterior surface and an interior surface;
• a gasket is disposed on the top surface of the lip;
• and
• connection bores are disposed within the base portion that align with corresponding connection bores on a top plate of the ion measuring device for selectively securing the base portion to the top plate of the ion measuring device.
