Page 14 1240 - Wireless Drop Bubble Counter Using the drop bubble counter for an accurate titration The drop counter counts individual drops as they pass through the light path of the counter. The sensor uses infra-red to count the drops. The drops to be counted must absorb some infra-red to change the light path intensity.
