| Logger Operating Range | -20° to 70°C (-4° to 158°F) |
| Buoyancy (Fresh Water) | 3.1 g negative (0.11 oz negative) |
| Depth Rating | IP68; waterproof to 122 m (400 ft) |
| Water Detection | Water conductivity level of 100 µS/cm or greater 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) |
| Transmission Range | Approx. 30.5 m line-of-sight (Approx. 100 ft line-of-sight) |
| Wireless Data Standard | Bluetooth Low Energy (Bluetooth Smart) |
| Logging Rate | 1 second to 18 hours |
| Time Accuracy | ±1 minute per month at 25°C (±1 minute per month at 77°F) |
| Battery | CR2477 3V lithium (user replaceable) |
| Battery Life |
3 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off disabled in software.
5 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off or Bluetooth Off Water Detect enabled in software.
Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life.
To ensure proper battery installation, see Battery Information for detailed instructions on replacing the battery in the MX2203 logger.
