Chauvin Arnoux CA 10141 [P01710020] Conductivity Meter. The CA 10141 is ideal for inspections and routine measurements of conductivity, TDS (Total Dissolved Solids), salinity, resistivity and temperature. Its numerous applications range from checking the threshold values for drinking water to the treatment of wastewater, whether in the field, in the lab or for the process. The CA 10141 is also used for measurements on natural waters thanks to its preset non-linear temperature compensation function compliant with the ISO/DIN 7888 standard.
