5-KEY BLOOD CELL COUNTER

A convenient table model that can be operated with either hand  having 5 keys and a totalizer unit to count the Basophils, Eosinophils, Monocytes, Lymphocytes 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.
