Multi-Function Drop Counter

Introduced in 2002 as the first of its kind for teaching laboratory interfaces, the Optical Drop Counter reduces the maintenance issues associated with wire-based devices that count by using drops to complete an electrical circuit. Unlike other devices, the counter's optical detector is sealed in an epoxy base to reduce the risk of spill damage from acids and bases. The device includes a holder for the pH probe and separate mount for temperature probes. Probe mounting and drop counting occur in a small-diameter area to reduce beaker size for titrations. An LED indicator mounted on the probe's top surface provides visual feedback when counting.
