Overview

HOBO MX800 Series multiparameter wireless data loggers work with interchangeable sensors to provide a highly configurable solution for monitoring water conductivity/salinity, temperature, depth, and dissolved oxygen. Available in both an easy-to-deploy, fully submersible model (MX801) and a direct read model (MX802) for convenient data offload that doesn’t require having to remove sensors from the water.

Features

Compatible with interchangeable Conductivity, CTD (conductivity/temperature/depth), and DO sensors (sold separately) - swap out sensors for different applications
Bluetooth, for easy logger configuration and data offload
Easy to deploy, fully submersible (MX801)
Direct read for convenient data offload (MX802)
Logger diameter is less than 2 inches
Faster data offload via Bluetooth 5.0
Water detect feature indicates when logger was out of the water (MX801)
Barometric pressure sensor included (MX802)
Connect two sensors to one logger to get measurements like salinity adjusted DO directly, with no need for post-processing
Guided calibration ensures accurate data
User-replaceable batteries

Specifications

MX801 and MX802

Operating Range: -40° to 50°C (-40° to 122°F), cannot be frozen in ice
Radio Power: 1 mW (0 dBm)
Transmission Range: 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 farther the device is from the logger

Barometric Pressure (MX802 only)

Measurement & Calibrated Range: 66 to 107 kPa (9.6 to 15.5 psia), -20° to 50°C (-4° to 122°F)
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

The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).

The UKCA marking identifies this product as complying with all relevant directives in the UK Declaration of Conformity.

* 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.
