HOBO pH and Temperature Data Logger
Item Code: MX2501
Bluetooth-enabled logger
A pH and temperature data logger for long-term monitoring of pH in water, leveraging Bluetooth for easy setup and data dowload.
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
- Water detection system for longer battery life and less maintenance
- Potentiometric pH electrode with plastic body, gel electrolyte, and double cloth junction
- User-replaceable battery, pH electrode, and anti-biofouling copper guard
- Accuracy of ±0.10 pH units within ±10°C of temperature at calibration
TECHNICAL SPECIFICATION
| Range | 2.00 to 12.00 pH |
| Accuracy | ±0.10 pH units within ±10°C of temperature at calibration |
| Resolution | 0.01 pH |
| Response Time | 1 minute typical to 90% at constant temperature in stirred water |
| Sample Ionic Strength | ≥ 100 µS/cm |
| Range | -2° to 50°C (28.4° to 122°F) |
| Accuracy | ±0.2°C (±0.36°F) |
| Resolution | 0.024°C at 25°C (0.04°F at 77°F) |
| Operating Range | -2° to 50°C (28.4° to 122°F) — non-freezing |
| 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). |
| Radio Power | 1 mW (0 dBm) |
| 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. |
| Memory | 152 KB (43,300 measurements, maximum) |
