Conductivity transmitter with temperature measurement LSP-TCT-3

Levtech Service & Prodtuction SRL Calibrations Calibration of the cell constant Every electroly c conduc vity cell has a constant (provided by the manufacture). This constant can be manually entered into the calibra on sec on, using the setup so ware or it can be calculated automa cally. The automa c calibra on of the cell constant is essen al periodically, due to the deposits or wear of the cells. Automa c calibra on for the high precision measuring is recommended even with the brand new cells because the cell constant can be diﬀer from the nominal value due to the manufacturing tolerances....
