The Maintenance Kit includes the Calibration Kit (MX2500-CAL-KIT) and the Electrode Storage Solution (MX2500-STORE-SOLN).
The Electrode Storage Solution is used to properly store and condition the pH electrode that is used with the HOBO MX pH Logger. The purpose of the storage solution is to maintain the hydrated gel layer that is integral to accurate pH readings.
The pH 4.01, 7.00, and 10.00 Calibration Solutions (475 mL bottles) are used to calibrate the pH electrode in the HOBO MX pH Logger.
The Calibration Kit includes pH 4.01, pH 7.00, pH 10.00 buffer solutions (475 mL bottles), and the 4 oz. calibration beaker (MX2500-CAL-BKR).
The Anti-Biofouling Copper Guard can be used in addition to the standard electrode guard for protection against biofouling during deployment. The anti-biofouling guard uses copper to reduce biofouling, while still allowing proper water flow to the sensor.
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 stored in storage solution when not deployed.
