LS225+N1500 is a split type plating thickness tester, which consists of the host and the digital probe N1500. It adopts the eddy current induction principle and has ultra-high measurement accuracy and repeatability which is especially suitable for measuring ultra-thin coatings and various small-sized work pieces and special-shaped materials.


The LS225+N1500 plating thickness tester can be used in production inspection, construction acceptance as well as sales and exhibition sites. It can quickly and non-destructively measure the thickness of non-conductive coating on non-magnetic metal substrates. This plating thickness measurement device can be used in industries such as aviation, building materials, machinery, chemicals, engineering and instrumentation, etc.

Digital probe ensures the data stability

N1500 is a digital probe that suitable for measuring the coating thickness and the digital signal is processed on the probe, which is not easy to be interfered by the external environment, ensuring good data repeatability

Ultra-thin anodized coatings can be measured

Using digital oscillation technology and high-speed ADC acquisition, the plating thickness measuring instrument can measure ultra-thin coatings below 10μm and ensure accurate and stable data

Continuous measurement support

LS225+F500 coating thickness gauge can continuously takes measurements which is ideal for analyzing large areas and gets one measurement result in 0.4 seconds

Optional fixture and clamp for stable measuring

Purchasing a dedicated test fixture can eliminate the error caused by human factors and the data repeatability can reach 0.1μm

Zero-adjustment and multi-point calibration support

Zero-adjustment and multi-point calibration to ensure more accurate data. LS225+N1500 coating thickness gauge is equipped with a special zero adjustment plate and standard film

Powerful data statistic function

With data statistics function, the plating thickness measuring instrument can automatically count the maximum, minimum, average and the standard deviation of the latest 9 sets of data
