Abstract: Pivoting leveling stand has a base with an outer, horizontal boundary; a pivot, downward of and in contact with the base, and positioned inwardly of the outer horizontal boundary of the base; and at least three leveling machines in contact with the base placed outwardly of the pivot. The pivot is capable of contacting an underlying support surface, and the leveling machines are attachable to an underlying support. As an option, from the base, preferably above the pivot, a fixture, for example, an upright rod such as for attaching a sensitive rotating viscometer, may be attached to the stand.

Abstract: A stator for a sensitive rotating viscometer is directly connected to the viscometer module housing or the viscometer module lower housing (rotor housing) particularly on lower portions or about the side of the same.

Abstract: A wall in a lower portion of a hollow support member having an open upper end and upper interior surface and a lower interior cylindrical surface to encircle and retain the stator of a rotating viscometer such as a Brookfield viscometer is provided with external threads and is slotted. A corresponding nut threads thereon and applies pressure to hold the stator of the viscometer.

Abstract: A sensitive rotating viscometer instrument generally having a housing surrounding a bath tub, the housing having a top upon which can be provided at least one sensitive rotating viscometer with a stator insertable through the top of the housing and into the bath, and which head remains above the top of the housing, includes at least one of the following features:(A) a conduit for supply of dry gas, extending under the top of the housing in a concealed or inconspicuous manner to couple near the viscometer head, for a dry gas blanket over the fluid to be tested in the stator;(B) an ergonomically positioned panel to include for at least one of the following: dry gas, power, and data transmission line control(s), coupling(s) and data display terminal(s) at highly visible, line of sight, and easily accessible position(s) above the top of the housing;(C) an offset viscometer head arrangement in which the locations of viscometer heads form symmetrically offset, non-rectangular rows or columns in an array when plural
