With its gel electrolyte and double Pellon® junction minimizing the chance of contamination of the reference electrolyte, this plastic-bodied electrode and the HOBO MX2501 pH and Temperature Data Logger are perfectly suited for environmental monitoring of streams, lakes, rivers, estuaries, and oceans. The electrode uses potentiometric and temperature measurements of samples to determine the pH, and can easily be replaced because of the simple plug-and-play 3.5-mm connector. Following proper calibration, storage, and maintenance protocols for the electrode, the MX2501 can achieve pH accuracies of ±0.10 pH units within ±10°C of temperature at calibration.

The replacement pH electrode replaces the original pH electrode that ships with the HOBO MX2501 logger. The electrodes should be replaced after six months of use.

Note: pH electrodes should always be kept in storage solution when not deployed.


Introducing - Onset HOBO pH and Temperature Data Logger

This video introduces the HOBO® MX2501 pH and Temperature Logger for long-term monitoring of pH in aquatic environments. The logger communicates wirelessly via Bluetooth Low Energy (BLE) to the HOBOmobile® app on a phone or tablet, making logger setup, calibration, and data offload quick and easy, with no need for extra equipment or complicated calibration procedures.



How to Calibrate the HOBO MX2501 pH and Temperature Data Logger

This video will guide you on how to properly calibrate the HOBO MX2501 Bluetooth pH and Temperature logger. Calibration is important to compensate for tolerances due to manufacturing, as well as for electrode aging, conditioning, and cleaning. It is also used to confirm the condition of the electrode.
