Product Summary
The Wireless Drop Counter has a wider (18 x 13 mm) drop window for better drop detection and easier alignment with burettes. It works equally well with large or small, fast or slow drops.
Measures up to 10 drops per second with drops as small as 0.5 mm.
Teaching Advantage
- IR filter assures accurate counts because room lighting cannot affect results
- Sensor unit can suspend two other probes in solution, simplifying many experiments
- Wider drop window (18 x 13 mm) means better drop detection and easier alignment with burettes
What's Included
- 1x Wireless Drop Counter
- 1x Micro Stir Bar
- 1x Drop Dispenser with Stopcock
- 1x Plastic Dispenser Rod Clamp

Visit PASCO's Experiment Library to view more activities.
High School / Chemistry
In this lab, students will complete a titration to determine the amount of chloride ion in water samples.
Advanced Placement • College / Chemistry
This lab is an introduction to Redox titration. Students use a redox probe and titration to determine the hydrogen peroxide content of a drugstore formulation.
High School / Chemistry • STEM
Students will be using a pH sensor, a drop counter, and Blockly coding to demonstrate the endpoint of a titration of an acid by a base.
Advanced Placement / Chemistry
In this lab, students use an oxidation reduction potential probe to expand their understanding of titrations, carry out a redox titration, and then use the redox titration method to answer a question of their own design.
Advanced Placement / Chemistry
Students use a pH Sensor and drop counter to determine the fundamental shape of a titration curve and the parameters that can cause it to change.
Advanced Placement / Chemistry
In this lab, students use a drop counter, conductivity sensor, and a temperature sensor to determine the concentration of dissolved ions by titration.
