CT2X Conductivity, Temperature Depth logger

Seametrics CT2X Conductivity, Temperature & Depth Logger

The Seametrics CT2X is a high-accuracy conductivity and temperature data logger with optional pressure/depth measurement, designed for long-term groundwater and surface-water monitoring.

Combining conductivity, salinity, TDS and temperature measurement in a compact submersible instrument, the CT2X is particularly suited to applications where changes in water quality need to be monitored alongside water level. Integrated logging, replaceable batteries and digital communications allow the CT2X to operate as either a standalone logger or as part of a remote monitoring system.

Applications

Typical applications include:

• Groundwater quality monitoring

• Saline intrusion studies

• Surface-water monitoring

• Contaminated land investigations

• Landfill monitoring

• Remediation monitoring

• Pumping and aquifer tests

• Quarry and mining applications

• Tidal and estuarine monitoring

Conductivity & Level Monitoring

Where specified with an integrated pressure sensor, the CT2X can simultaneously monitor conductivity, temperature and water level, providing a useful indication of both hydraulic and water-quality changes from a single instrument.

This makes the CT2X particularly useful for monitoring saline intrusion, contaminant migration, groundwater/surface-water interaction and changes associated with pumping or remediation activities.

Flexible Monitoring & Telemetry

The CT2X can operate as a standalone logger for periodic data download or be integrated into remote monitoring and telemetry systems using Modbus RTU or SDI-12 communications.
