- Approximately 30.5 m (100 ft) line-of-sight
- Wireless Data Standard
- Bluetooth 5
- Number of sensors that can be connected
- 2
- Maximum Cable Length
- 120m (400 ft)
- Logging Rate
- 5 second to 18 hours
- Logging Modes
- Fixed interval (normal or statistics), burst, or multiple intervals with up to 8 user-defined logging intervals and durations, 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 a set logging period
- Water Detect
- Events are logged when logger is submerged or removed from the water (MX801 only)
- Time Accuracy
- ±1 minute per month 0° to 50°C (32° to 122°F)
- Battery
- Four AA, 1.5 V lithium batteries, user replaceable
- Battery Life
- With W-CTD or W-CT sensors: 2 years, typical with 1-minute logging interval or slower
With W-DO sensor: 1-year, typical with 5-minute logging interval or slower
Faster logging or statistics sampling intervals, entering burst logging mode, excessive readouts, and remaining connected with the app will impact battery life - Memory
- 730,000 measurements, divided between channels (4 Mbyte memory)
- Data Download Time (with Bluetooth 5+ devices)
- Full memory: Approximately 3.5 minutes
120,000 measurements: 1 minute
May take longer the further the device is from the logger

- Accuracy*
- Typical error: ±0.2 kPa (0.029 psi)
Maximum error: ±0.5 kPa (0.073 psi) - Resolution
- <0.01 kPa (0.0015 psi)
- Pressure Response Time**
- <1 second to 90% at a stable temperature
- Contribution to Water Level Accuracy***
- Typical error: ±0.075% FS, 0.3 cm (0.01 ft) water
Maximum error: ±0.15% FS, 0.6 cm (0.02 ft) water

* Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.
** Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes.
***Water Level Accuracy: With accurate reference water level measurement, known water density, and a stable temperature environment. System Water Level Accuracy equals the sum of the Barometric Water Level Accuracy plus the selected CTD sensor Water Level Accuracy.
