Mobile Leeb
hardness tester
SAUTER HMM

Impact (rebound) sensor: The bounce module is accelerated by a spring against the item being tested. Depending on how hard the object is, the kinetic energy of the module will be absorbed. The speed reduction will be measured and converted to Leeb hardness values.
External impact sensor (Type D) included
Automatic recognition of the impact (rebound) sensor connected to the HMM.
Mobility: The SAUTER HMM. provides a professional and resilient measurement solution wherever required, i.e. production, product control etc.
All measurement directions possible (360°) thanks to an automatic compensation function
Data output to PC: USB output included
Wireless IR printer included for on-site printing of measurement protocols (battery operated)
Standard block and support ring for curved surfaces (Radius > 10 mm)
Support rings for bended testing samples available on request
Delivered in a hard carrying case
Internal memory for up to 9 data groups, with up to 9 values per group forming the average value of the group
Mini statistics function: Displays the measure value, the average value, the difference between the maximum and minimum values, date and time
Measurement value display: Rockwell (B & C), Vickers (HV), Brinell (HB), Shore (HSD), Leeb (HL), tensile strength (MPa)
Automatic unit conversion: The measuring result is automatically converted into all specified hardness units
