Overview of the HOBO MX2501 Bluetooth pH & Temperature Data Logger
The Onset HOBO MX2501 is a pH and temperature data logger designed for long-term monitoring of pH levels in estuaries, lakes, streams, rivers, and oceans. Harnessing Bluetooth Low Energy (BLE) technology the MX2501 communicates wirelessly with the free HOBOconnect app on your mobile device or Windows computer. The app makes logger setup, calibration, and data offload quick and easy. The app guides you through the pH calibration process making an otherwise complicated process much easier to follow. This cost-effective compact data logger dramatically reduces the time and effort needed to collect field data, and at the same time providing higher resolution data.
