Pencatat data nirkabel multiparameter seri HOBO MX800 bekerja dengan sensor yang dapat diganti untuk menyediakan solusi yang sangat mudah dikonfigurasi untuk memantau konduktivitas/salinitas air, suhu, kedalaman, dan oksigen terlarut. Tersedia dalam model yang mudah dipasang dan sepenuhnya dapat direndam (MX801) dan model pembacaan langsung (MX802) untuk pengunduhan data yang mudah tanpa perlu mengeluarkan sensor dari air.
| Specification | Details |
|---|---|

| Transmission Range | Approximately 30.5 m (100 ft), line-of-sight |
| Wireless Data Standard | Bluetooth 5 |
| Number of Supported Sensors | Up to 2 sensors |
| Maximum Cable Length | 120 m (400 ft) |
| Logging Rate | 5 seconds to 18 hours |
| Logging Modes | Fixed interval (normal or statistics), burst, or multiple intervals (up to 8 user-defined intervals with pause and repeat options) |
| Start Modes | Immediate, next interval, or date & time |
| Stop Modes | Memory full, never stop (overwrite oldest data), date & time, or after set logging period |
| Water Detect | Events logged when submerged or removed from water (MX801 only) |
| Time Accuracy | ±1 minute per month (0° to 50°C / 32° to 122°F) |
| Power | |
| Battery Type | Four AA, 1.5 V lithium batteries (user replaceable) |
| Battery Life | With W-CTD or W-CT sensors: 2 years (1-minute logging interval or slower) With W-DO sensor: 1 year (5-minute logging interval or slower) Faster logging, burst mode, excessive readouts, or continuous app connection will reduce battery life. |
