01 A convenient table model
that can be operated with either hand, having 8 keys and 1 totalizer
unit, for use with a microscope to count the Meta-Myelocytes, Basophil,
Monocytes, Lymphocytes, Polycytes and a window for other mIscellaneous
cells. Each key can record up to 999 with the exception of the totalizer
unit which records the total number of strokes made on all the other
keys. At totals of 100, 200, 300, etc., the totalizer unit rings a bell.
The keys are positioned low, allowing the wrist to rest on the table and
registers are located above the corresponding key for continuous
visibility. A reset knob at either end of the counter can turn all the
keys to zero.
02 Similar to the above, but having 5 keys and a totalizer unit
to count the Basophils, Eosinophils, Monocytes, Lymphocytes and a window
for other miscellaneous cells.
