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

Operating Range: -40° to 50°C (-40° to 122°F), cannot be frozen in ice

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
