Complete your water data

The HYDROS 11 Electrical Conductivity and Temperature Sensor is designed to measure the electrical conductivity of water in a pipe or tank. When you pair the new ES-2 with a TEROS 12 soil moisture sensor in the soil, you’ll begin to develop a complete picture of the salts that are going into your system, as well as the salts remaining in your soil or substrate.

Check your irrigation water quality from anywhere

The four-electrode array on the body of the HYDROS 11 measures water salinity from 0 to 120 dS/m. Connect the sensor to a ZL6 data logger subscribed to ZENTRA Cloud, so you can skip the site visit and monitor this indicator of water quality from any web connected device.

Consistent measurements at any temperature

The HYDROS 11 is designed to operate at temperatures from –40 °C (–40 °F) to 60 °C (140 °F), and internal circuits automatically normalize salinity measurements to their equivalent at 25 °C. This ensures you always have the most accurate data to guide your irrigation and additive strategies.

Feature summary

• Plug-and-play with ZL6 data loggers and compatible with SDI-12 systems
• Measures EC at a resolution of 0.001 dS/m for precise monitoring of fertilizers and other additives draining from soil
• Simplify spot checks of EC and temperature data by using a ZSC handheld sensor interface
