  • Description
    Four electrode conductivity cells for universal applications
    Conductivity measuring cells with graphite electrodes with four electrodes for standard measurements in aqueous solutions in the field and in the lab

    - No measuring errors due to cable, polarization effects or changes of the electrical boundary field
    - Highest precision and linearity
    - Long-term stable cell constant thanks to graphite electrodes
    Four -electrode conductivity cell with built-in temperature sensor, IP 68 (2 bar), cell constant K = 0.475 cm-1
    TetraCon® 325: 1.5 m cable and waterproof plug
    TetraCon® 325-3: 3 m cable and waterproof plug
