GFS DRAFT ENCLOSURE AND VIBRATION ISOLATION
TABLE
The GFS balance, AMH, and reference gas cylinder assembly are operated inside an insulated enclosure
to isolate them from air drafts and rapid changes in temperature or humidity.
The entire enclosure is placed on a granite vibration isolation table, which further stabilizes the
temperature inside the enclosure. The granite table top measures 600mm x 900mm x 150 mm (23.6” x
35.4” x 5.9”) and has ledges which are used as a connection point for the draft enclosure mounting
brackets. The table top rests on a steel stand.
