QNix@4500 coating Thickness Gauge is widely used in the field of coatings and automotive coatings, QNix@4500 is a magnetic induction and eddy current dual-purpose coating Thickness Gauge, this model is a standard version of the integrated probe, can not only be used to measure magnetic substrates such as steel, but also can be used to measure aluminum, copper, stainless steel and other non-magnetic metal surface coatings, oxide film, phosphate film and other coatings. These two models are simple to operate, easy to carry, and have high precision, which are loved by the majority of users.

1. Simple and fast measurement
2. No calibration is required
3. Automatic power on/off
4. Large range FE: 0-5000um NFE: 0-3000um
5. Dual-purpose probe, cost-effective
6. Hall sensor makes the measurement more stable
7. The sound is synchronized during measurement
8. Ruby wear-resistant head, long life
9. Backlight LED display, the reading is clearer
10、Automatic recognition of the measurement substrate
11. Split probe to meet different measurement environments
Type F:
Measure the thickness of non-magnetic coating layers on ferromagnetic metal substrates such as steel and iron, such as: paints, powders, various anti-corrosion coatings, plastics, rubber, synthetic materials, phosphating layers, chromium, zinc, lead, tin, cadmium, etc.;
Type N:
Measure the thickness of all non-conductive layers on non-ferromagnetic metal substrates such as copper, aluminum, stainless steel, etc., such as: paints, powders, various anti-corrosion coatings, plastics, rubber, synthetic materials, phosphate layers, oxide layers, etc.;
