Portable Hardness Tester is used to measure hardness of metal. Conventional hardness testers, like Rockwell, Brinell or Vickers machines, require the test piece be brought to the testing device; but this is not always possible. Portable testing devices have been developed that permit in-situ hardness measurements thus offering quick and economical supplements to conventional, stationary testing machines. Measured hardness number can be easily converted into any other scale like Rockwell, Superficial Rockwell, Brinell or Vickers. Direct impression method has various probes for different loads and controlled with the load cell mechanism. These lightweight testers can be carried to any site with ease. They are equipped with an LCD operating console, user friendly interface with easy test settings and generate clear results, real time statistics and graphs. These testers are operative up to 360° degrees of positioning, even upside down. In compliance with ASTM E110 and ISO 50157 hardness standards, it can do hardness testing on almost all metals: chromed surfaces, nitrided surfaces, aluminium, brass, copper, bronze, metal wire, ceramic items, glass materials, hard/soft steel and hard/soft plastic.
