Abstract:
1. A modular conductivity sensor, comprising: a probe body having a distal end and a proximal end, the distal end defining a first opening, the first opening being surrounded by a recessed portion forming a shoulder, the probe body having a set of internal threads disposed thereon and having a set of external threads disposed thereon, the probe body having a chamber extending to the first opening; and an electrode tip assembly having a distal end and a proximal end, the tip assembly including a body formed of an insulating material, the body having a set of threads capable of engaging with the internal threads in the probe body, the tip assembly having a head with a diameter that is greater than the body so as to form a shoulder, the body having at least one opening extending to at least one chamber, the electrode tip assembly having at least one electrode disposed in the at least one chamber in the body, the at least one electrode having a first end extending beyond the distal end of the tip assembly and having a connection terminal disposed at the proximal end of the assembly.
