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.
