The   9074,   8074,   7074   and   6074   Three Arm   Caliper   logging   tools,   are   a   three- arm     caliper     configuration     used     to measure   the   diameter   of   the   borehole. They    can    be    used    in    both    open    and cased   holes.   Natural   Gamma   and   the casing     collar     locator     are     optionally available.      However,   when   configured with     both     the     natural     gamma     and casing   collar   locator   the   tool   is   slightly longer.
