LS225 High Precision Coating Thickness Gauge for Ultra-thin Layers



The LS225+N1500 is a versatile, portable eddy current thickness gauge, featuring the LS225 host and the N1500 non-ferrous probe. Its probe-style design makes it perfect for measuring coating thickness on small or irregular workpieces. For ultra-thin coatings below 10μm, the LS225+N1500, used with a test fixture, offers outstanding repeatability of 0.1μm. This thickness gauge provides fast, non-destructive measurements of non-conductive coatings on non-ferrous metal substrates, such as anodized layers on aluminum components or protective coatings on PCB surfaces, ensuring precise and reliable results.


1. Accurately and consistently obtain data for coatings with thicknesses below 10μm.

2. The probe's minimum measurement area is 7 mm, making it suitable for testing small-sized materials.

3. Utilizing cutting-edge digital probes guarantees precise test results.

4. Featuring data statistics, LS225 calculates maximum, minimum, average, and standard deviation values.

5. It facilitates zero adjustment and multi-point calibration for enhanced data precision.

6. The option of dedicated fixtures minimizes error sources, achieving data repeatability up to 0.1μm.

7. The instrument ensures it can pass tests by authoritative metrology institutes.
