The HOBO MX2501 pH and Temperature Data Loggers are designed for long-term monitoring of pH in both freshwater and
saltwater environments. The MX2501 features Bluetooth Low Energy® (BLE) technology. The pH Logger communicates
wirelessly with the free HOBOmobile® app on iOS 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 in data.
