Heathrow Scientific Hand Tally Counter | HS6594 — Count one event at a time
Manufacturer product/application view. Consult the stated order unit and supplied contents; illustrated accessories are a representative setup.

Count one event at a time

A hand counter is useful when the same observation repeats: bacterial colonies, blood cells, drops of liquid or another event defined by your procedure. It provides a running total while you concentrate on recognizing the next event. Establish what qualifies as one count before starting; the counter records your input rather than identifying a colony or classifying a cell.

Keep the display and grip accessible

The reading lens helps you see the tally, and the finger ring provides a secure grip. The body measures 4.6 cm in diameter by 4.1 cm wide. Check that the grip and viewing position suit the person doing the work, especially when the count takes place beside a microscope or another instrument that already occupies the work surface.

Reset only after recording the result

The quick-reset knob prepares the counter for another run. Write down or otherwise record the completed tally before resetting, following your laboratory recordkeeping procedure. For work that requires separate totals for different categories, a multi-key differential counter is a more appropriate format than trying to assign several categories to this single running total.
