    Product description

    HOBO MX800 Series wireless data loggers work with interchangeable sensors to provide a highly configurable solution for monitoring water conductivity/salinity, temperature, level, and dissolved oxygen (coming soon). 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

    Manual

    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 further 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
