Instrumentation embraces an at least partially automated rotational tapered bearing simulator viscometer having electronic control and/or monitoring that includes task unit electronics, which includes a task unit electronics interface. With or without such electronics, the instrumentation may include a particular component configuration and/or employ at least one particular material. Further feature(s) may be extant.

Instrumentation that embraces a rotational viscometer, or that has a cantilevered platform elevator and/or employs heat in one area but not another

Apparatus includes a pivotable, cradling framework that can hold a rotatable bomb instrument, which can include a hollow cylinder and a grease rack. This may be employed to effect a significantly improved version of the ASTM D942 Test Method. The same is useful in measurement of grease oxidation.
