    Multi 3320 Glossary Glossary pH/ORP/ISE Asymmetry see zero point Electromotive force of The electromotive force U of the electrode is the measurable electromo- an electrode tive force of an electrode in a solution. It equals the sum of all the gal- vanic voltages of the electrode.
  • Page 100 Glossary Multi 3320 Conductivity Cell constant C Characteristic quantity of a conductivity measuring cell, depending on the geometry. Conductivity Short form of the expression, specific electrical conductivity. It corresponds to the reciprocal value of the resistivity. It is a measured value of the ability of a substance to conduct an electric current.
  • Page 101 Multi 3320 Glossary Channel A channel is a display indication that corresponds to a physical connec- tion on the meter. Measured parameter The measured parameter is the physical dimension determined by measuring, e.g. pH, conductivity or D.O. concentration. Measured value The measured value is the special value of a measured parameter to be determined.
