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.

Advanced Placement / Earth & Environmental
In this lab, students will collect and analyze three soil samples to determine their quality based on macro and microscopic observations, CO2 production, soil pH, and soil salinity.
High School • Middle School / Chemistry • Physical Science
Students will use a pH sensor to determine the pH of common household substances.
High School / Earth & Environmental
In this lab, students will investigate the conductivity and pH of local water sources before determining the buffering capacity of each sample using a weak acid.
High School / Earth & Environmental
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 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.
