This four-ring conductivity probe offers a versatile and accurate solution for TDS readings. A 4-ring electrode design allow for reduced polarization and surface coating effects over an extended linear range of measurement. The probe comes with a protective PVC sleeve that assures durability when taking measurements outdoors and a 1m (3.3”) cable for accessing samples. Four-ring probe reduces polarization PVC body for increased durability DIN connector Skip to the end of the images gallery Skip to the beginning of the images gallery More Information
