86220H Dry Film Thickness Gauge
High Accuracy and Stability
Accurately measures coatings on both ferrous and non-ferrous substrates.
Measurement range for dry film thickness: 0–2000μm.
The 86220H is a high-precision, integrated coating thickness gauge that utilizes both the Hall effect and eddy current measurement principles.
Using the Hall effect, it measures non-ferromagnetic coatings on ferromagnetic metal substrates. With eddy current technology, it measures non-conductive coatings on non-magnetic metal substrates.
At room temperature, the only ferromagnetic metals are iron, cobalt, nickel, and gadolinium.
Common non-ferromagnetic metals include copper, aluminum, zinc, and chromium.
Hall Effect: Suitable for measuring non-ferromagnetic coatings on ferromagnetic substrates.
Eddy Current: Suitable for measuring non-conductive coatings on non-magnetic metal substrates.

FAQ
-
1. The difference between 86220H and 86221
The functions and parameters of 86220H and 86221 are exactly the same, but the 86220H coating thickness gauge adopts an integrated design and can be operated with one hand; while the 86221 adopts a split design, the probe size is smaller, which is suitable for measuring narrow spaces and some special positions.
