Titration experiments are core to any chemistry curriculum – now conducting a titration has never been easier! The Wireless Drop counter counts drops of titrant added during a titration and converts the drops into a volume. Use the Wireless Drop Counter, with a Wireless pH sensor, Wireless Temp sensor or Wireless Conductivity Sensor to easily perform potentiometric, thermometric and conductometric titrations.
- Measures up to 10 drops per second
- IR Filter assures accurate counts because room lighting cannot affect results
- Sensor unit can suspend up to two other probes in solution, simplifying many experiments
- Wider drop window (18 x 13 mm) means better drop detection and easier alignment with burettes
- Splash resistant design to keep it safe from harm in wet labs
- Automatically recalibrates for maximum sensitivity each time the unit is turned on.
- LED drop indicator makes setup and testing easy
- Long-lasting rechargeable battery (>200 hours on a single charge)
- Included materials make it easy to set up a drop dispenser and easily control drop size and flow
- 1x Wireless Drop Counter
- 1x Micro Stir Bar
- 1x Drop Dispenser with Stopcock
- 1x Plastic Dispenser Rod Clamp
- Investigating indicators
- Chemical reactions
- Counting drops and measuring volume
Includes a Micro Stir Bar for even better titration data. The Micro Stir Bar connects to the end of your pH or Conductivity probe and maintains a constant constant flow of solution over the end of the electrode. Works with a standard stir plate. (Additional Micro Stir Bars are also available separately.) It also includes a Drop Dispenser plus a stainless steel rod for easy attachment to a ring stand.

Battery and Logging
|Stored Data Points Memory (Logging) 1||Not Supported|
|Battery – Connected (Data Collection Mode) 2||>260 hr|
|Battery – Logging (Data Logging Mode) 3||Not Supported|
1 Minimum # of data points with all measurements enabled, actual results depend on enabled measurements.
2 Continuous use in a connected state until battery failure, actual results will depend on sample rate, active measurements, and battery condition.
3 Logging until battery failure, actual results will depend on sample rate, active measurements, and battery condition.
* Normal classroom use is the sensor in active use for 20min/lab for 120 lab periods/yr.
Perform the following experiments and more with the Wireless Drop Counter.
Visit PASCO’s Experiment Library to view all activities for this product.
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.
Students will use a pH sensor and a drop counter to explore the shape of a titration curve produced by a strong acid and a weak acid when titrated by a strong base.
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.
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.
In this lab, students use a drop counter, conductivity sensor, and a temperature sensor to determine the concentration of dissolved ions by titration.
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.
