A pH and temperature data logger for long-term monitoring of pH in water
Data Loggers & Remote Monitoring Solutions

Onset HOBO MX pH and Temperature Data Logger

The HOBO MX pH and Temperature logger is designed for long-term monitoring of pH in aquatic systems. With a replaceable pH electrode and an anti-biofouling copper guard, this durable logger can be deployed in both fresh and saltwater environments. This logger is Bluetooth® Low Energy (BLE)-enabled for wireless communication with a mobile device or computer. Using the HOBOconnect® app, you can easily calibrate and configure the logger, download logged data to your phone, tablet, or computer, or automatically upload the data to HOBOlink® for further analysis. You can also configure the logger to calculate statistics, set up alarms to trip at specific thresholds, or enable burst logging in which sensor readings are logged at a faster interval when the pH or temperature rises above or falls below certain limits.
