note：This product does not support 110V voltage. Please do not place an order if the voltage is not compatible, otherwise you will need to provide your own transformer. Ultra-High Precision: Offers display accuracy of up to 0.01μm to detect minute surface variations. Measurement range covers Ra 0.05-10.0μm and Rz 0.1-50μm, fulfilling the demands of high-end machining and quality assurance. Seven Key Parameters: Measures Ra, Rz, Rq, Rt, Rp, RV, and RC, enabling comprehensive analysis of surface quality beyond just single metrics for a thorough evaluation of mean deviation and peak/valley height. Fast & Reliable: Equipped with a high-speed DSP processor for quick data processing, delivering accurate results within seconds. Reduces waiting time for batch tests and enhances quality control efficiency with consistent readings. Clear OLED Display: Designed for use in both low and high-temperature environments. The high brightness and contrast of the display ensure readability in various lighting conditions, minimizing visibility-related errors.
