GL- HYUT400 Ultrasonic hardness tester

NDT On-site testing equipment Main Features:

• Standard: DIN 50159-1-2008; ASTM-A1038-2005; JB/T 9377-2010; JJG-654-2013; GB/T34205-2017.
• Calibration by 10 Vickers hardness blocks with different hardness values.
• According to the different elastic modulus of the material using a point calibration, eliminating the effect of the elastic modulus, to achieve the test accuracy.
• Multi-point calibration is adopted due to the conversion error of each hardness system of the hardness conversion table, the thickness of the workpiece, the roughness of the surface of the workpiece, and the measurement error brought about by the influence of liquid flow inside the workpiece. Direct calibration of HRC, HRB HRA HB HV 
• For composite materials or new materials without hardness value conversion table, using multi-point calibration to directly test HRC, HRB HRA HB HV and other hardness system.
• can measure HV, HRC, HRA, HRB, HB and other hardness system.
• support 360 °, as long as the indenter and the measured surface into 90 ° ± 5 ° angle, you can carry out the measurement operation.
• the main interface of the screen directly displays the current measurement value, the cumulative number of measurements, the maximum value, the minimum value, the average value, the measurement data is automatically saved, the measurement time, the material, the hardness conversion table standard.
• battery specifications: 3.6V, 3000mAh lithium battery, battery life of 15 hours.
• data storage: can store 50 groups of measurement data and 10 calibration file data.
• 11, can be connected to an external Bluetooth printer to print the measurement data (optional) or connect the computer super terminal to export the measurement data.
• the test indentation is small: the indentation is smaller than the Richter hardness tester, need to use a high power microscope to observe.
• fast measurement speed: can be in 2 seconds to output test results.
