| Resolution | <0.085 kPa (0.012 psi), 0.87 cm (0.028 ft) water | |||
| Pressure Response Time (90%)*** | 1 second at a stable temperature | |||
| Logger | |
| Operation Range | -20° to 50°C (-4° to 122°F) |
| Radio Power | 1 mW (0 dBm) |
| Transmission Range | Approximately 30.5 m (100 ft) line-of-sight |
| Wireless Data Standard | Bluetooth Low Energy (Bluetooth Smart) |
| Logging Rate | 1 second to 18 hours |
| Logging Modes | Fixed interval, multiple intervals with up to 8 user-defined logging intervals and durations, or event-triggered burst |
| Memory Modes | Wrap when full or stop when full |
| Start Modes | Immediate, date & time, or next interval |
| Stop Modes | When memory full, stop with HOBOmobile, date & time, or after a set logging period |
| Time Accuracy | ±1 minute per month 0° to 50°C (32° to 122°F) |
| Battery | Two AA, 1.5 V alkaline batteries, user replaceable |
| Battery Life | 1 year, typical with logging interval of 1 minute. Faster logging and/or statistics sampling intervals, entering burst logging mode, excessive readouts, checking of Full Status Details, and remaining connected with HOBOmobile will impact battery life. |
| Memory | 256 KB memory (30,000 sets of measurements) |
| Full Memory Download Time | Approximately 2 minutes; may take longer the further the device is from the top end of the logger |
