| Logger Operating Range |
-20° to 70°C (-4° to 158°F) |
| Logging Rate |
1 second to 18 hours |
| Buoyancy (Fresh Water) |
MX2203: 3.1 g (0.11 oz) negative |

| Waterproof |
MX2203: To 122 m (400 ft) |
| MX2204: To 1,524 m (5,000 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). |
| Memory |
96,000 measurements |
| Battery |
CR2477 3V lithium, user replaceable in MX2203, non-replaceable in MX2204 |
| Battery Life |
3 years, typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always On 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 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 MX2204 logger. |
| Time Accuracy |
± 1 minute per month at 25°C (77°F) |
| Full Memory Dowload |
Approximately 45 seconds; may take longer the farther the device is from the logger |
