Wireless pH Sensor with Digital Display

Product Code: PS-4204


PASCO’s best tool for measuring pH since litmus paper, now with a digital display for instant readings! Manually record data using the display, or wirelessly transmit pH values to a device to graph and analyze using software.

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. With a lithium ion battery; the device will be measuring for years. 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. Bright OLED display allows students to immediately investigate solution properties with or without a computer interface.

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.


  • Simply charge, pair and go, no cables or interfaces to manage
