Conductivity calibration results to judge whether sensors are acceptable or not. X-axis is conductivity on standard sensor, Y-axis is conductivity differences of SBE41 and standard sensor. and ▲ represent SBE-Calibration and J-Calibration results (S/N 914, 918, and 922), respectively. Colors (dark blue, light blue, and green) indicate sensor S/N (914, 918, and 922), respectively. + means J-Calibration only for APEX (dark orange) and Navis (purple) type floats. The result of SBE calibration for each sensor is shown as a line graph (7 conductivity/temperature points). Area within red dotted lines defines acceptable Argo accuracy, while the area within red dashed lines defines acceptable accuracy requiring re-calibration at least twice
