Operating principle An E.C. (electrical conductivity) probe measures the electrical conductivity in a solution. It is commonly used in hydroponics, aquaculture and freshwater systems to monitor the amount of nutrients, salts or impurities in the water. Inside the conductivity probe, two electrodes are positioned opposite from each other, an AC voltage is applied to the electrodes causing cations to move to the negatively charged electrode, while the anions move to the positively electrode.
A conductivity probe is a very simple device. It is just two conductors with a fixed surface area at a fixed distance from each other. This distance and surface area is known as the conductivity cell. The cells distance and surface area is quantified as the conductivity cells K constant. How often do you need to recalibrate a conductivity probe? Conductivity probes work by measuring the electrical current of the water between two graphite plates.
Extending the probe cable length You can extend the cable to greater than 100 meters with no loss of signal. Atlas Scientific has tested up to 300 meters without a problem, however you run the risk of turning your E.C. probe into an antennae, picking up noise along the length of your cable. If you want to extend your cable, we recommend that you use proper isolation, such as the Basic EZO TM Inline Voltage Isolator, or Tentacle Shield. Be sure to calibrate your probe with the extended cable.
Helpful operating tips Be sure to watch out for air bubbles, as they can get caught between the two graphite plates and throw off your results. Lightly tap your conductivity probe to knock out any bubbles caught in the probe. Bubbles Probe cleaning Over time conductivity probes can become dirty and covered in deposits, which can change the basic electrical properties of the probe and cause inaccurate readings. Soft coatings can be removed by lightly brushing around the conducting area.
Hard coatings should be chemically removed. We highly recommend you use the Atlas Scientific conductivity probe cleaner.
