SUNNYSONG Professional Surface Roughness Tester

• 1. A handheld instrument suitable for production site environment and mobile measurement needs, it can measure the surface roughness of many kinds of machine tool machined parts, can calculate the corresponding parameters according to the selected measurement conditions, and display all the measurement parameters and contour graphics on the monitor.
• 2. Simple operation, comprehensive functions, fast measurement, stable accuracy, easy to carry, can measure the main parameters of the new international standards, the full and strict implementation of international standards.
• 3. Can measure the workpiece range: plane, external surface, tapered surface, bore, groove, surface, etc. (special surface needs to be measured with applicable sensors)
• 4. Split design: composed of host, driver and sensor, can measure the roughness of the inner wall of pipes with an inner diameter greater than 40mm, with a delay line of 1m, which can be increased to 3m.
• 5. The roughness measuring head employs a high-precision inductive sensor with an integrated diamond stylus, delivering stable and accurate measurements. Equipped with standard calibration blocks featuring analog waveforms, it serves as a high-precision roughness measuring instrument.
• 6. If the instrument is running normally, we guarantee the replacement for 3 months and the warranty for two years (except for perishable and consumable items, such as sensors, cables, etc.), and lifetime service.

 Surface Roughness Tester with Detachable Drive is a high accuracy instrument for measuring surface roughness. It can be used on variety of machining parts and operates on various surfaces, not only flat but also outer cone, outer cylinder, curved, pinholes, grooves, recesses grooves and axle etc.
