Product Summary
The Wireless pH Sensor is a must-have for any chemistry, biology, or environmental science course. Equally capable in the lab or field, the sensor eliminates the hassle of cables, reducing spills and improving safety. Don't worry about charging, the sensor has a coin-cell battery that lasts for 2-3 years in most labs and costs about one dollar to replace. The sensor can transmit data in real-time, or store data for hours or days when continuous monitoring is required. The Wireless pH Sensor can perform countless experiments, including acid-base titrations, investigating household chemicals, changes in pH during reactions, water quality studies, and much more.
The Wireless pH Sensor uses a BNC connector to attach the pH probe. This amplifier can be used with other probes as well, such as ORP, Flat pH, and ISE electrodes. Please see the buying guide for a full list of compatible accessories.

Experiment Library
Perform the following experiments and more with the Wireless pH Sensor.
Visit PASCO's Experiment Library to view more activities.
Soil pH
Students use a pH sensor to investigate how local soil quality may impact the ability to support agricultural crops.
Monitoring Water Quality
In this lab, students use a water quality sensor, turbidity sensor, and weather/anemometer sensor to monitor the pH, dissolved oxygen content, conductivity, and turbidity of a natural body of water. Students will use their data...
Diffusion
Students use a pH sensor to investigate the diffusion of hydrogen ions through a semipermeable membrane, comparing the rates of diffusion for two solutions that differ in their acidity.
Air Pollution and Acid Rain
In this lab, students will use pH sensors to determine the effect air pollutants (CO2, SO2, and NO2) have on the pH of water.
Modeling an Ecosystem
In this lab, students use a variety of sensors to explore the use of terrariums as a closed system for environmental studies and design methods for exploring the interrelationships of biotic and abiotic variables within ecosystems.
Le Chatelier's Principle
In this lab, students will use a pH sensor to determine how concentration changes effect the equilibrium of a system. Students will relate pH values with the acid-base indicator phenolphthalein.
