GENERAL INFORMATION
The AE-Corr-Ohmeter AECO 220 measures corrosion in any environment both aqueous and non-aqueous liquids, mixed phases, vapours, gases, atmosphere and solids. The ER 7428 works in connection with a probe installed in a corrosive environment. The probe employs a sensing element made from wire, strip or tube of the same metal as the pipeline, vessel or structure to be monitored. As corrosion occurs, the cross-sectional area of the sensing element decreases and its electric resistance increases according to Ohm’s law. The AE-Corr-Ohmeter AECO 220  circuit measures with very high precision the variation of electrical resistance of the sensing element, it calculates the variation of its cross-sectional area and gives the attack penetration with a sensitivity of 1/10,000 of its original diameter. A digital display of corrosion penetration allows easy and precise readings for the operator. A single instrument can be used to measure an unlimited number of probes installed at different locations of a system or systems: Each Probe can be distinguished by a unique TAG number and measures are memorised in a non-volatile memory.

APPLICATIONS
The AE-Corr-Ohmeter AECO 220 is used for both laboratory and field, it measures corrosion in:
□ pipeline □ refinery □ chemical and petrochemical plant process equipment □ measures pollution and corrosive effects of air in the atmosphere □ measures erosion in high velocity streams detects water traces in chlorinated hydrocarbons and in dry gases.
The AE-Corr-Ohmeter AECO 220  is also used to control the effectiveness of:
Corrosion inhibitors
Cathodic and anodic protection systems
Control of process variables and measures the corrosion in:
Pipelines
Process equipment 
Mixed phases, both liquid and gaseous
Liquids, both aqueous and non-aqueous
Atmosphere
