AMI Deltacon DG Safety Instructions 1.3. Restriction for use The AMI Deltacon DG is designed for determination of: specific (total) conductivity cation (acid) conductivity after the cation exchanger degassed conductivity after a sample reboiler in water-steam- cycles only.
Product Description 2.1. Description of the System Application The AMI Deltacon DG is a complete monitoring system for the auto- matic, continuous measurement of the conductivity before (specific Range conductivity) and after a cation exchanger (cationic or acid conduc- tivity) and the conductivity of the re-boiled sample (degassed con- ductivity).
