Overview
Designed for long-term monitoring of pH in estuaries, lakes, streams, rivers, and oceans. This logger leverages Bluetooth technology to communicate wirelessly with Onset's free HOBOconnect app running on your mobile device or Windows computer, making logger setup, calibration, and data offload quick and easy. Plus, a guided pH calibration process in the HOBOconnect app makes an otherwise complicated process easier to follow. This affordable, compact logger delivers high resolution data and dramatically cuts the time and effort needed to collect it.
Features
- Guided pH calibration following on-screen prompts in HOBOconnect app
- Rugged PVC housing for deployment in both freshwater and saltwater environments
- Quick and easy data offload via Bluetooth to mobile devices or Windows computers

| Logger | ||
| Operating Range | -2° to 50°C (28.4° to 122°F) — non-freezing | |
| Depth Rating | IP68; waterproof to 40 m (131 ft) | |
| Water Detection | Water conductivity level of 100 µS/cm or greater is necessary for reliable detection of water. Deionized water or water below 100 µS/cm may not be detected. The water conductivity circuit may not reliably detect water that has frozen around the electrodes, i.e. below 0°C (32°F). | |

| Transmission Range | Approximately 30.5 m (100 ft) line-of-sight in air | |
| Wireless Data Standard | Bluetooth Low Energy (Bluetooth Smart) | |
| Logging Rate | 1 second to 18 hours | |
| Logging Modes | Fixed interval (normal, statistics) or burst | |
| Memory Modes | Wrap when full or stop when full | |
| Start Modes | Immediate, push button, date & time, or next interval | |
| Stop Modes | When memory is full, push button, date & time, or after a set logging period | |
| Time Accuracy | ±1 minute per month 0° to 50°C (32° to 122°F) | |
| Battery Type | One AA 1.5 Volt, user-replaceable | |
| Battery Life | 1 year typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always On selected in software. 2 years typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Off Water Detect enabled in software. 3 years typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off selected in software. Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life. | |
| pH Electrode Typical Minimum Life | 6 months in sample with ionic strength ≥ 100 µS/cm | |
| Memory | 152 KB (43,300 measurements, maximum) | |
| Full Memory Download Time | Approximately 60 seconds; may take longer the farther the mobile device is from the logger | |
| Dimensions | 22.86 x 4.27 cm (9.0 x 1.68 inches); mounting hole 0.64 cm (0.25 inches) | |
| Weight | 268.2 g (9.46 oz) | |
| Buoyancy | Fresh water: 13.6 g (0.48 oz) negative Salt water: 19.6 g (0.69 oz) negative | |
