The CS547A is a water quality probe that measures both electrical conductivity (EC) and temperature. It connects to a Campbell Scientific datalogger via the A547 interface. This probe is compatible with most Campbell Scientific dataloggers.
Benefits and Features
- Compatible with most Campbell Scientific data loggers
- Easy to clean
- Corrosion resistant
- Rounded ends facilitate installation and removal
- Compatible with AM16/32-series multiplexers allowing measurement of multiple sensors
- Weighted option available for stand-alone submersion
The CS547A measures temperature with a thermistor. Electrical conductivity (EC) is measured with three cylindrical stainless-steel electrodes mounted in an epoxy housing. The electrode configuration eliminates ground loop problems associated with sensors in electrical contact with earth ground. The electrodes are ac coupled, and the datalogger applies a bipolar excitation. This process reduces electrochemical reactions, minimizes corrosion, and extends the probe’s life.
The CS547A is easy to clean and resistant to corrosion. It has rounded ends to facilitate installation and removal. The CS547A is shipped with a cell constant calibrated in a 0.01 molal KCl solution at 25°C. The solution has an EC of 1.408 mS cm-1.
