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.
Able to measure up to 40 events 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

Product Guides & Articles
AP Chemistry Lab Manual Overview
Authored by chemistry educators, the Advanced Chemistry Through Inquiry Teacher Lab Manual includes sixteen guided inquiry labs that cover AP Chemistry course concepts such as Moles and Molar Mass, Stoichiometry, and Reaction Rates.
pH Sensors & Probes
A pH sensor is a type of probe used to measure the pH of solutions in chemistry, biology, and other science applications. pH probes are often used to determine the basicity or acidity of an aqueous solution.
Titration
A titration is a chemical analysis in which a researcher determines the concentration of a chemical solution (analyte or titrand) by adding a measured volume of standard solution (titrant) until the produced reaction reaches the equivalence point.
Experiment Library
Perform the following experiments and more with the Wireless Drop Counter.
Visit PASCO's Experiment Library to view more activities.
Blockly Extension: Determination of Titration Endpoint
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.
An Acid-Base Titration
In this lab, students will use a drop counter and pH sensor to determine the concentration of a hydrochloric acid solution and an acetic acid solution by titration.
How Much Acid is in Your Fruit Juice?
Students use titration and a pH sensor to study the organic acid content of fruit juices.
Stoichiometry in Solutions
Students use conductometric titration and particle modeling to study the stoichiometry of acid-base titration.
How Hard is Your Tap Water?
Students use conductometric titration and gravimetry to determine how much calcium carbonate is in a sample of tap water.
Investigation of Acid-Base Titrations
Students compare the pH titration profiles of strong, weak and polyprotic acids.
Weak Acid Titration
In this lab, students will use a drop counter and pH sensor to titrate monoprotic and polyprotic weak acids. Then they'll determine the relationship between the shapes of the curves and Ka.
Shape Of Titration Curves
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.
Diprotic Titration: Multi-Step Chemical Reactions
In this lab, students will use a drop counter and pH sensor to determine the concentration of a sodium carbonate solution. Students will learn that chemical reactions can be the sum of several individual reactions.
Double Replacement Reactions
In this lab, students will complete a titration to determine the amount of chloride ion in water samples.
Percentage of H₂O₂ in Drugstore Hydrogen Peroxide
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.
Titration Curves
Students will use a pH Sensor and a Drop Counter to explore the shape of a titration curve produced by the titration of a strong acid and a weak acid by a strong base.
