Technical data
Type 8202/8222
Redox potential measu-
rement (8202)
• Measurement range
• Resolution
• Measuring error
• Recommended min.
divergence of the redox
potential range associated
to the 4-20 mA signal
• -2000 mV to +2000 mV
• 1 mV
• ±3 mV
• 50 mV (eg: range 1550 to
1600 mV associated to the
4-20 mA output current)
Conductivity measu-
rement (8222)
• Measurement range
• Resolution
• Measuring error
• Recommended min.
divergence of the
conductivity range asso-
ciated to the 4-20 mA
signal
• 0,05 µS/cm to 10 mS/cm
• 1 nS/cm
• ±3 % of the measured value
• 2 % of the full scale (e.g. for the
sensor with C=0.1: range from
100 to 104 µS corresponds to the
4-20 mA output current)
