Overview

The conductivity sensor is an interchangeable sensor that works with HOBO MX800 Series Water Loggers to measure conductivity and temperature. With this sensor attached to a HOBO MX800 Series Water Logger, the logger can also calculate specific conductance, salinity, and total dissolved solids (TDS).

The conductivity sensor can be attached directly to the fully submersible MX801 model, or attached via cable to the direct read MX802 model, which doesn’t require having to pull the sensor out of the water to download data.

Features

4-electrode conductivity sensor provides wide measurement range for monitoring freshwater or saltwater
Conductivity sensor is centrally located to minimize effects from stilling wells or protective guards
1” diameter for use in narrow wells (with cable to MX802 above the well)
Temperature sensor placement near the sensor tip for fast fast response time
Specially treated stainless steel holds up in saltwater
