What parameters do ECTD-30V and ECTD-60V measure?

The sensors measure electrical conductivity, temperature and water level (depth) in groundwater and surface water applications.

What is the conductivity range?

The conductivity measurement range is 5 to 120,000 µS/cm.

How is barometric correction handled?

Option I uses an absolute pressure sensor with an individual barometric sensor in the datalogger. Option II uses a gauge pressure sensor with vent tube and desiccant chamber.

Can data be transmitted remotely?

Yes, using GSM/GPRS telemetry, data can be transmitted to a central or cloud server in near real-time.

Model ECTD-30V and ECTD-60V CTD sensors are available for monitoring electrical conductivity, water level, and temperature in the ground. These are arerobust, marine-grade sensors.

The Model ECTD-30V CTD probe comes with the Model EPP-30V absolute pressure sensor, and the ECTD-60V CTD probe comes with the Model EPP-60V absolute pressure sensor. The ESDL-30CTDB datalogger, which collects the data from these sensors, has much of the complex circuitry, lowering the cost of individual sensors without impacting their accuracy or resolution.
