9.2 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
0.01 cm -1 or approx. 50 μS/cm for cell constant 0.1 cm -1 using a reference measuring system
traceable to NIST or PTB. The exact cell constant is entered into the quality 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 quality
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 quality
certificate supplied. The uncertainty of measurement in determining the cell constant is
1.0 %.
