Overview
The CS547A probe monitors the electrical conductivity (EC) and temperature of water. 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 a bipolar excitation is applied. This reduces electrochemical reactions, minimizes corrosion, and extends the probe’s life. Temperature is sensed with a thermistor.
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.
Key Advantages
Epoxy housing is durable and easy to clean
Technical Description
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 data logger 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.
