NFT Pitting (Differential) — NORTEC 600D Model
This near-field testing (NFT) application uses a differential configuration to detect
internal pitting in finned air-cooler tubing (also referred to as “fin-fan”) [see
Figure 5-221 on page 279].

The near-field testing (NFT) eddy current technology is a rapid and inexpensive
inspection solution designed specifically for ID defect detection in carbon steel finned
tubes (see Figure 5-222 on page 280). NFT probes reduce inspection cost and improve
ease-of-use.
