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 (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.

Key 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.

Requires the free HOBOconnect mobile app (available from iTunes and Google Play).

Pre-assembled Logger & Sensor Options 

For your convenience, the MX801 multi-parameter data logger is available for purchase in the pre-assembled logger and sensor configurations below:

Access your data directly from your mobile phone, tablet, or Windows computer when within 100 foot line-of-sight range of the logger - with the free HOBOconnect app.

To enable cloud data storage and analysis - add an MX Data Plan (select from options above).

To enable near real-time remote monitoring and alerts via email/text message - add an MX Data Plan and MX Gateway (select options above). Note: The MX Gateway must be indoors.

Explanation

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

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.
