Test Rough Surfaces in Seconds! “I recently used this while working on a custom woodworking project where getting a smooth finish was crucial. This tester gave me quick precise measurements, so I knew exactly when the surface was at the quality level I needed. It’s easy to use and the portability means I can bring it with me wherever I work. This tool has been great for my projects making it easy to ensure professional quality work every time.” -Gary E. Why Get Our Surface Roughness Tester? ✅ Precise and Portable: Traditional surface inspection tools are often bulky or slow, which slows down your process and reduces accuracy. This compact tester gives you 0.01μm accuracy, one-button measurement, and fast results powered by a high-speed DSP processor. It fits easily in your hand or pocket for quick testing wherever you go. ✅ Fast and Easy to Use: The high-speed DSP chip ensures stable, quick calculations. OLED screen shows results clearly, and the lithium-ion battery keeps you working longer with simple USB charging and auto-shutoff features. ✅ Versatile Across Applications: Measures Ra, Rz, Rq, and Rt on flat, grooved, cylindrical, and non-metal surfaces. Use it for quality control in automotive, aerospace, machining, and more. Works on parts over 80 x 30 mm and adapts easily between projects. 🌟HOW TO USE First, slide the measuring area to the right to expose the sensor. Keep the sensor clean and covered when not in use to protect its precision. Next, place the tester flat and steady on the surface you want to measure. Make sure it’s not tilted or unstable. Lastly, press the measurement button to begin. Avoid touching the device or surface while it’s measuring. The result will appear on the screen automatically. 📓FREQUENTLY ASKED QUESTIONS Q: Can I use this tester on non-metal surfaces?A: Yes, it’s designed to measure both metal and non-metal surfaces, including flat, curved, or grooved types. Q: How will I know if it detected a rough surface?A: After measurement, the tester will show numerical values for Ra, Rz, Rq, or Rt on the screen. The higher the number, the rougher the surface. For example, the device can measure Ra values up to 15.0μm and Rz up to 50.0μm. Surfaces that reach these higher values are considered very rough, while lower values indicate a smoother finish. ⚙️ Specifications: Color: Red Item Weight: 7.04 ounces Measuring Range: Ra, Rq: 0.05~15.0μm; Rz, Rt: 0.1~50.0μm Indication Accuracy: 0.01μm Sample Length: 0.25, 0.80, 2.50mm Evaluation Length: 1.25, 4.0, 5.0mm Stroke Length: 6mm Variability:
