Water quality monitoring is the primary way of identifying water pollution. The parameters most commonly monitored include water temperature, pH, dissolved oxygen. Temperature influences the quantity of dissolved oxygen that water is able to contain. pH affects many biological processes in the water. A large variety of aquatic habitats prefer a range of 6.5 to 8.0 pH.

The HOBO MX2501 pH and Temperature data logger is an affordable and compact logger for long-term monitoring of pH in estuaries, lakes, streams, rivers, and oceans. Using Bluetooth Low Energy® (BLE) technology, the MX2501 pH Logger communicates wirelessly with the free HOBOconnect app. Logger setup, calibration, and data offload can be done quickly and easily using your mobile phone and Windows computer. A guided pH calibration process on the HOBOconnect app makes an otherwise complicated process easier to follow. This affordable and compact logger dramatically cuts the time and effort needed to collect field data, while also offering higher resolution data. (NOTE: pH electrodes should always be stored in storage solution when not deployed.)
