Refer to cell specifications for details.The multipoint calibration option on the YSI Model 3200 Conductivity Instrument gives greaterflexibility and performance when using one cell over a wide conductivity range. This featureallows users to calibrate one cell with up to 5 different conductivity standard solutions. Whenanalyzing a sample, the instrument selects the calibration value that is closest in conductivity tothe sample.3200 S ERIES CONDUCTIVITY CELLSDip cells are generally used for routine conductivity measurements. The 3254 Fill Cell isdesigned for small sample or high throughput work. It requires only 5 ml of sample and cantake measurements quickly from one sample to the next.The 3255 Flow Cell is designed for in-line conductivity measurements, such as forultrapure water systems.YSI Incorporated Model 3200 43
