High quality special glass. The gel-filled (non-refillable) electrode that does not need maintenance and with a double protection gasket that gives it a longer life.

The soil electrode is manufactured with a housing that gives it resistance to breakage, this electrode also works in solution but it takes longer to take the pH measurement.

Do not forget to clean the electrodes after each measurement with a cleaning solution as well as to calibrate the meter once a month with pH4 and pH7 liquids as well as liquid to calibrate Ec meters.
Remember that an incorrect level of Ec and pH in any type of crop leads to a nutritional imbalance of the plants, affecting their health and development.
