  • MX2500-ELECTRODE

    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.

  • T-SDX-93030-010

    The SDX is a “Wet-Wet” device. While it is important to keep the SDX cable’s vent tube unobstructed for barometric pressure compensation, neither the pressure transducer nor internal electronics are damaged by condensation or moisture entering the vent tube. For best results, we recommend the desiccant cartridge with vent tube adapter.

  • RS3

    Use the RS3-B Solar Radiation Shield to protect your external sensors from sunlight and rain. This shield ensures users gain more accurate measurements, due to increased airflow around sensors. And users benefit from 2.5 times faster response time to changing conditions. 

    The RS3-B Solar Radiation Shield works with most of Onset’s external temperature and temperature/relative humidity, including those for our award-winning HOBO Weather Station products.

    For customers interested in deploying a radiation shield with Onset data logger such as a HOBO Pendant or U-Series data logger, Onset also offers two other models of solar radiation shields; the RS1 and the pre-assembled M-RSA
