Cable, length 3 m, instrument side with open wire.
1) Uncertainty of ±5 % arises when using only one single cell constant for the
full range. ±0.5 % measurement deviation can be achieved when calibration
is performed in a conductivity range close to that of the used solution.
2) Nominal cell constant.
Every product is measured according to a Bürkert standard procedure
and the individual cell constant measured is reported in the calibration
report, delivered with the product. The cell constant can be influenced by
the assembly situation.
