Most of the A&D Series
of precision balances are equipped with a standard built in
underhook. These include:
Series of Precision High Capacity Toploading Industrial
Balances can be purchased with an optional underhook.
The EK-6000G/12KG can be purchased with
the optional EKW-07G under
hook assembly. The EKW-07G is attached to the bottom
of the main unit for weighing large objects that are difficult
to load on the weighing pan. The under hook assembly
allows for large object and magnetic material to be weighed
in suspension. The EK4000-H and
EK6000H can also be purchased with the optional EK-07H under hook assembly.
makes density determination a relatively simple matter. The
steps outlined below explain just how easy the weigh below
can find the underhook behind the plastic plug on the under-side
of your HM, HR, HF, HFG series balance. The EK6000/12KG,
EK4000H/EK6000H and the GP-Series offer the underhook optional and you should have it installed.

place the balance on a firm metal stand designed for underhook
a light-weight weighing harness from the underhook, or thread
a strand of thin string/wire through the underhook.
