Claim:
A sensor head apparatus employable with a multi-parameter monitoring tool assembly, comprising: a sensor head body configured with a plurality of ports, where each of the plurality of ports is configured to engage and interconnect with an interchangeable sensor head component, whereby each of the plurality of ports is sized to receive one end of the interchangeable sensor head component, and engagement and disengagement of the interchangeable sensor head component within the plurality of ports occurs through application of a linear force upon the interchangeable sensor head component; wherein the plurality of ports are each configured to receive and engage an insertable portion of the interchangeable sensor head component, wherein a radially compressible sealing device is disposed around the insertable portion; and wherein the sensor head body further includes at least one atmospheric pathway incorporated therein which interconnects the plurality of the ports so as to distribute atmospheric gasses which may be compressed during engagement and interconnection of the interchangeable sensor head components in any of the plurality of ports.
