HOBO pH and Temperature Logger Model MX2501

Designed for long-term monitoring in estuaries, lakes, streams, rivers, and oceans, this logger measures pH and water temperature. Bluetooth Low Energy® (BLE) connectivity allows the logger to communicate wirelessly with iOS devices through the free HOBOmobile® App. Use the app for easy logger setup, step-by-step calibration, and fast data offload. The logger’s 152 KB memory stores up to 43,300 measurements. Equipped with a rugged PVC housing, the logger is waterproof to 40 meters (131.2 feet) and can be deployed in freshwater or saltwater environments. The pH electrode features Pellon® junctions, gel electrolyte, and a glass sensor bulb.

Note: This data logger requires the HOBOmobile App and a compatible mobile device.
