Description
EC-2500L – Logging Electrical conductivity sensor
The EC-2500L is a logging electrical conductivity sensor is designed and made in Australia, for long-term deployment in the field. Featuring both a digital conductivity and temp sensor it is well suited for low power operations where access and site visits are limited.
Unlike conventional electrode-based cells, the encapsulated toroid design requires very little maintenance, ensuring many years of accurate data collection without recalibration, and the delrin-tube design and embedded temperature sensors avoid issues of degradation due to corrosion.
The full-scale range of the sensor is specified and calibrated from the factory (choose a full-scale range from 500 to 75,000µS/cm) and the temperature sensor can be factory set to compensate the EC output reading.
The sensor is available with a sealed cable of customer-specified length as standard, or it can be optionally fitted with a waterproof socket, and a matching cable plug can be supplied.
The EC-2500L has an integrated data logger that can be programmed to record at intervals which suit your requirements. The recorded measurements can be extracted via an optional SDI-12 adaptor. For clandestine monitoring, it is possible to integrate batteries to power the logger (negating the need for solar panels) for long-term, discrete deployment.
Optional Extras for EC-2500L
Features include:
- Digital Logging electrical conductivity sensor which can be installed in active waters (acidic or salty conditions)
- A reliable and robust sensor ensures minimal servicing visits
- Suitable for marine applications and waterways with high sediment loads
