The HH-411 Impact Type Hardness Testing Unit is designed for portability, as it is ideal for testing large samples on site. It is simple to operate, by pressing the detector against a sample surface, and pushing the detector button with one's finger, as if pressing a ballpoint pen. The detector can be manipulated to measure various shapes, and can be used for workpieces such as grooves and gear teeth.
The HH-411 is also equipped with an automatic orientation corrector, that compensates for gravitational discrepancies and provides accurate measurement readings. It also come with a data-save function that can store up to 1800 hardness test results on the device.
