MULTIFUNCTIONAL MEASUREMENT: The Surface Roughness Gauge is capable of measuring a wide range of surface roughness parameters including RA, RZ, RY, RO, RT, RP, RV, RMAX, R3Z, RSK, RS, RSM, and RMR. EXTENSIVE DATA STORAGE: This profiler can store up to 100 sets of measurement data along with their corresponding waveforms, making it highly effective for record-keeping and data analysis. It also features a USB interface for easy data transfer and external connectivity. SURFACE ROUGHNESS ANALYZER: Designed to measure the surface roughness of machined components, this device computes and displays all relevant parameters and graphics based on selected settings. RECHARGEABLE BATTERY: Equipped with a built-in lithium-ion rechargeable battery and charging control circuit, it offers a large capacity and eliminates memory effect, providing over 20 hours of continuous operate.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. EASY-TO-USE DESIGN: The large LCD screen shows the profile curve and all parameter values in real-time. Its intuitive menu and high-definition color display make it the tool for engineers, quality inspectors, and maintenance professionals.
