The ultrasonic hardness tester is using ultrasonic contact impedance method to compare and test patterns, this is an innovative design of auto-calibration of probe, presents advantages of high precision, fast speed, easy operation, etc.
3 User materials with setup guide was included, in addition, the hardness measurement covering most ferrous metals, non-ferrous metals and their alloys in industrial production.
It is applicable in hardness test of flange edges, root of gear groove, stamping parts, thin plates, for surface-hardened gear grooves and its taper parts, as well as shafts, thin-walled pipes, turbines.etc.
Features
- Accord to the Testing Standard GB/T 34205-2017
- For materials with different elastic modulus, provide multi-point calibration function for any hardness standard based on your standard hardness samples.
- Support hot-swap and self-calibration: automatically + by manual identifies the probe
- The material function includes 3 new material settings to facilitate hardness testing of special materials
- The display adopts IPS (In-Plane Switching) full digital LCD display with wide viewing angle, and the back light can be adjusted arbitrarily
- USB communication interface allows for data exchange with PC and to set up on PC.
- The upper and lower limits of the hardness value can be pre-set, and an automatic alarm will be issued if the range is exceeded, which is convenient for users to meet the needs of batch testing
- 600 sets of hardness measurement data each includes measurement date, sensor type, material, number of times, single measurement value, average value, maximum value, minimum value, hardness scale and other information
