Compact and lightweight, easy measurement! Portable micro-sphere rebound testing machine.
The 『eNM3A10』 is a micro ball rebound testing machine capable of testing small, light, and thin objects, which traditional rebound testing machines have struggled with. (Reduction of mass effect) The indenter is a commercially available alumina ball with a diameter of 3 mm, and replacement is very easy. Moreover, it is economical and has excellent shape accuracy. No special anvil (receiving platform) is required during calibration. Measurements can also be taken while holding the sample in hand. 【Features】 ■ Portable and easy to measure "hardness" and "rebound coefficient" on-site ■ Measurements can be taken in all directions ■ Continuous measurements are possible ■ Minimal indentation on the sample ■ Samples thicker than 5 mm can be measured without a base (for steel) *For more details, please download the PDF or feel free to contact us.
