Corrosion potential, concrete resistivity and permeability testers
Service life and durability assessment of reinforced concrete structures
The construction industry is rapidly moving towards performance based specifications for concrete durability of new structures; at the same time the assessing of service life of actual reinforced concrete elements is being a subject of increasing concern in the industry. Half-cell potential, concrete resistivity and concrete cover air permeability are the main and most widely accepted indicators of likelihood of corrosion and estimated durability of a concrete structure.
Proceq’s Profometer Corrosion, Resipod and Torrent instruments are designed and manufactured to assess the durability of concrete structures by measuring corrosion potential, concrete resistivity and permeability.
