Model: RD-ETTS02

All-in-One Water Sensor

One probe for electrical conductivity, total dissolved solids, salinity and temperature.

Request a quote

The RD-ETTS02 combines several water measurements in one compact probe: electrical conductivity (EC), total dissolved solids (TDS), salinity and temperature. It is used in environmental monitoring, aquaculture and industrial water management, and its design is easy to install for continuous monitoring. It connects to a SpaceEcho station and reports to EchoCloud.

Combining water quality sensors

These three probes measure different parameters, so they are used together rather than instead of each other.
