ABSTRACT:
The specification discloses an electronic manually operated blood cell counter including continuous count capability in response to a single key depression for recording large number of similar cells during a differential count. More specifically, the counter includes microprocessor control for periodically incrementing a counter in response to sustained depression of a manually actuated counting switch. The control is adjustable to vary the speed at which the counter is periodically incremented to accommodate individual laboratory technicians.
