Performance characteristics

9.2.1 Uncertainty of measurement
CLS15D
Each individual sensor is factory-measured in a solution of approx. 5 μS/cm for cell constant
-1
0.01 cm or approx. 50 μS/cm for cell constant 0.1 cm
traceable to NIST or PTB. The exact cell constant is entered into the manufacturer inspection
certificate supplied. The uncertainty of measurement in determining the cell constant is
1.0 %.
CLS16D
Each individual sensor is factory-measured in a solution of approx. 5 μS/cm using a reference
measuring system traceable to NIST or PTB. The exact cell constant is entered into the
manufacturer inspection certificate supplied. The uncertainty of measurement in determining
the cell constant is 1.0 %.
CLS21D
Each individual sensor is factory-measured in a solution of approx. 5 mS/cmusing a reference
measuring system traceable to NIST or PTB. The exact cell constant is entered into the
manufacturer inspection certificate supplied. The uncertainty of measurement in determining
the cell constant is 1.0 %.
