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. Plus, it rarely requires charging; the sensor's coin cell battery lasts for 2-3 years in most labs and costs about one dollar to replace. It can transmit data in real time, or store data for days when continuous monitoring is required. The Wireless pH Sensor enhances countless activities, including acid-base titrations, investigations into household chemicals, analyses of chemical 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 the ORP, Flat pH, and ISE electrodes. Please see the buying guide for a full list of compatible accessories.

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.
Acid-Base Chemistry
Acid-base chemistry is present everywhere in our daily lives. Many substances are acidic and basic, while others are neutral. The determining factor that makes a substance an acid or a base is the amount of hydrogen ions or hydroxide ions present.
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.
