Claim:
1. A machine fluid testing probe, comprising: a handle; a shaft connected to the handle and extending outwardly from handle, the shaft having a first end proximate to the handle, a second end opposite the first end, and a length extending between the first end and the second end, a first portion extending from the first end toward the second end, a second portion extending from the first portion toward the second end, and a shoulder defined by the second portion of the shaft at an intersection of the first portion and the second portion, the first portion having a first cross-sectional axis, the second portion having a continuous arcuate external surface having a second cross-sectional axis greater than the first cross-sectional axis and extending across the continuous arcuate external surface, wherein the shaft is configured to be removably positioned to contact a machine fluid of a machine; and a plurality of indicators supported by the first portion of the shaft between the first end and the second end so as to contact the machine fluid, each of the plurality of indicators configured to test for one or more contaminants in the machine fluid, wherein a first indicator of the plurality of indicators has at least a first indicator cross-sectional axis which is smaller than the second cross-sectional axis of the second portion of the shaft whereby the first indicator at least partially defines a recess.
