Features
- Replacement pH electrode
- Gel electrolyte and double Pellon junction
- Accuracy of ±0.10 pH
HOBO MX2500 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. 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.
