QuaNix 4200 是德国尼克斯公司推出的一款专业涂层测厚仪，广泛应用于制造业、金属加工、化工、商检等多个领域。该仪器采用先进的霍尔原理，能够无损地测量磁性金属基体（如钢、铁等）上的非磁性涂层厚度。其测量范围为 0-3000μm，精度极高，0-50μm 时误差不超过 ±1μm，50-1000μm 时误差不超过 ±1.5%，1000-3000μm 时误差不超过 ±2%。

QuaNix 4200 的一大亮点是无需校准，只需在测量前进行零位校准即可，避免了传统测厚仪因标准片失效带来的误差。此外，它还具备温度补偿功能，可在 0℃-50℃的温度范围内保证测量精度。仪器的探头采用耐磨的红宝石材质，使用寿命长，测量结果更加稳定。QuaNix 4200 操作简单，自动开关机设计，方便快捷。其一体化设计，体积小巧（100×60×27mm），重量仅约 110 克，便于携带。

The QuaNix 4200 is a professional coating thickness gauge launched by the German company Nix. It is widely used in manufacturing, metal processing, chemical industry, and commercial inspection. Based on the advanced Hall principle, this instrument can measure the thickness of non-magnetic coatings on ferromagnetic metal substrates such as steel and iron. With a measurement range of 0-3000μm, it boasts high precision. The error is less than ±1μm when measuring thicknesses between 0-50μm, less than ±1.5% for 50-1000μm, and less than ±2% for 1000-3000μm.

One of the highlights of the QuaNix 4200 is that it does not require calibration. It only needs zero calibration before measurement, avoiding the errors caused by the failure of standard pieces in traditional thickness gauges. Moreover, it features temperature compensation, ensuring measurement accuracy within a temperature range of 0℃-50℃. The probe of the QuaNix 4200 is made of wear-resistant ruby, which ensures a long service life and stable measurement results. The instrument is easy to operate with an automatic on/off design for convenience. Its integrated design, compact size (100×60×27mm), and light weight (approximately 110 grams) make it portable.
