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.

High School / Environmental Science
In this lab, students will model several water treatment methods. Then they will use pH, conductivity, and turbidity sensors to assess the effectiveness of each filter.
High School / Chemistry
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.
Advanced Placement / Environmental Science
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.
High School / Chemistry
In this lab, students will use a pH sensor and common household chemicals to relate pH and hydronium ion (H3O+) concentration. Students will classify solutions as acidic, basic, or neutral.
High School / Chemistry
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.
Advanced Placement / Chemistry
In this lab, students use a pH sensor to learn how a compound's structure influences its solubility in water and oil.
