Pre-oxidized PAN carbon yarns with metal reinforcement, impregnated with powder of graphite.
The graphite packing C8300R is braided with pre-oxidized PAN carbon yarns with metal reinforcement. The packing is impregnated strand by strand with a special colloidal graphite compound to give extreme compactness while ensuring flexibility to its body. It can be easily cut and installed and is also available in the C8200 version without metal reinforcement.
C8300R is a versatile compression packing that can be used for all static services in presence of steam, air, gas, oils, bitumen, petroleum and chemical products with the exception of those oxidizing and not compatible with graphite.
Introduction The Proceq Profometer 4 is a widely used non-destructive testing (NDT) instrument designed to locate and estimate the depth of steel reinforcement in concrete structures. As bridge decks, parking garages, building slabs, and other reinforced concrete elements age, accurate knowledge of rebar position and cover thickness becomes critical for assessing durability, planning repairs, and ensuring structural safety. This essay describes the Profometer 4’s capabilities, typical applications and workflow, advantages and limitations, and its broader impact on structural inspection practice.
(If you need a user manual-style summary or step-by-step operating checklist formatted for printing, I can produce that next.)
Conclusion The Proceq Profometer 4 is a practical, field-ready electromagnetic cover meter that contributes valuable information to concrete inspection and maintenance workflows. While it cannot replace complementary NDT techniques for complex investigations, its portability, speed, and non-destructive operation make it an essential instrument for locating reinforcement, estimating cover, and preventing damage during construction activities. Operators should be mindful of the device’s limitations, perform proper calibration, and combine Profometer data with other assessments to achieve robust structural evaluations.
