The HOBO MX2501 pH and Temperature data logger is designed for long-term monitoring of pH in estuaries, lakes, streams, rivers, and oceans. Leveraging Bluetooth Low Energy (BLE) technology, the MX2501 pH logger communicates wirelessly with the free HOBOmobile app on iOS and Android devices, making logger setup, calibration, and data offload quick and easy. A guided pH calibration process on the HOBOmobile 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.

You can download the HOBOmobile app for free for Android devices here and for iOS devices here.

The Hobo MX Gateway (purchased separately) can be used to aggregate the data from up to 100 Hobo MX data loggers directly to a PC via Ethernet or WiFi communications.
