331 Approximately 25” - 37” (64-94 cm)

For Permanent Fixtures

The 331 Type pedestal stands are ideal for permanent installations requiring excellent stability and a short, adjustable height instrument stand. This stand has a working height range from a minimum of 24" (61 cm) to a maximum of 36" (91.4 cm), not including any adapters which may be mounted on top of the intermediate tube. This height measurement is taken from the floor to the top of the intermediate tube, on which all instrument mount accessories are attached. Custom heights are easily manufactured.

A variety of stand adapters, slides, lifts, and various instrument mounts fit into the intermediate tube. The stand has an air cushion damper to prevent the column from "free falling" and damaging the instrument if the collar lock, ratchet pawl, and lift handle are released at the same time.

The baseplate is a 1" (2.54 cm) thick steel plate with a diameter of 15" (38.1 cm). Four 1-1/16" (2.7 cm) mounting holes are equally spaced on an 11" (27.9 cm) diameter bolt circle on this baseplate. It is also outfitted with four 5/8"-11 UNC-2B threaded leveling screws on a 14” (35.6 cm) diameter bolt circle to provide a means for adjustment to set the stand vertical.

Stands in this group are used for permanent installations of all types of metrology instrumentation and are often used in test, calibration, or constant monitoring applications.
