Recommended fields of application

The TetraCon

®

700-...Ex conductivity measuring cell is suitable for 

stationary measurements in water/wastewater applications.

Characteristics

The principle of the measurement method makes it possible to avoid 
influences from primary or secondary polarization effects. This ensures 
a high degree of measuring accuracy.

The modern epoxy casting technique reduces the danger of breaking 
the conductivity measuring cell in rough industry use.

1.3

Variants and identification

Instrument identification

The instrument designation is printed on the plug-sided end of the 
cable. The series number is engraved in the closing head. Have these 
designations ready in case of queries to the WTW service department.
