A metallic probe body formed of a pipe plug with an upper cylindrical cavity intersected by lower passageways carrying insulating members. Metallic terminal pins extend through these members for mounting field-replaceable electrodes in a side-by-side relationship. An electrical fitting is secured to the top portion of the plug for enclosing the cavity. Electrically conductive means in the cavity interconnect the electrical fitting and the pins. The conductive means are insulated from one another and the probe body. The probe body may be readily installed in any piping system carrying corrosive fluids without introducing any weakness into such piping. The pipe plug subcomponent of the probe body can be manufactured by available pipefitting techniques.
