Technical Description

microLAB’s Drop Counter uses an infrared light emitting diode and a photo-transistor to count individual drops. An LED flashes on the drop counter for each drop detected. A background correction circuit subtracts ambient light from the sensor’s view while another circuit eliminates false counts from fragmented drops.
