Overview
This fully assembled data logger is ready to deploy for monitoring conductivity, salinity, and depth (CTD) while still offering the flexibility to add further parameters like dissolved oxygen (DO) using the 2-sensor adapter. Also calculating specific conductance, salinity, and total dissolved solids (TDS), this logger records absolute pressure, which is later converted to water level readings by HOBOconnect software.
To compensate for barometric pressure changes, you can use a HOBO MX20L Water Level logger as a barometric reference.
The fully submersible, Bluetooth-enabled MX801 multi-parameter data logger is highly accurate and easy to deploy. Complete with simple setup and data offloading using a wireless connection to a compatible mobile device or Windows computer using the free HOBOconnect app. Learn more.
Key Features
- 4-electrode conductivity sensor provides wide measurement range for monitoring freshwater or saltwater
- Conductivity sensor is centrally located to minimise effects from stilling wells or protective guards
- Durable ceramic water level sensor, located in the sensor tip for accurate measurement of shallow water levels
- Temperature sensor placement near the sensor tip for fast response time
- Bluetooth, for easy logger configuration and data offload
- Specially treated stainless steel holds up in saltwater
- Logger diameter 1 inch for use in narrow wells
- User-replaceable batteries.
Requires the free HOBOconnect mobile app (available from iTunes and Google Play).

The MX801 logger records absolute pressure, which is later converted to water level readings by HOBOconnect software. To compensate for barometric pressure changes, you can use a HOBO MX20L Water Level logger, recommend the MX20L-04 for highest accuracy, as a barometric reference. The barometric reference device is typically deployed in the same well or at the same location as the water level of interest, but rather than being placed in the water column, it is deployed above the water in air. Since barometric pressure readings are consistent across a region (except during fast-moving weather events), you can generally use barometric pressure readings that are taken within 15 km (10 miles) of the logger or more without significantly degrading the accuracy of the compensation. This means you only need to use one MX20L logger as a barometric reference for any loggers within this range. |
