Here’s the best tool for measuring pH since litmus paper. The Wireless pH Sensor connects via Bluetooth® to monitor the pH of solutions.
See the Buying Guide for this item's required, recommended, and additional accessories.
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 days when continuous monitoring is required. The Wireless pH Sensor performs acid-base titrations, investigation of 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.
