CF series Cryogenic temperature use strain gauge

CF series cryogenic temperature use strain gauges utilize a special plastic for the backing and a special alloy for the element. They allow stable measurement from normal temperature to the cryogenic temperature range. The temperature compensation range is an approximate range.

Applicable specimen Metal, Ceramics
