Ultrasonic Portable Hardness Tester with Test Force 20N Probe (Manual) 2kgf
Introduction:
- 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.
- The hardness measurement covers most ferrous metals, non-ferrous metals and for 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 it's taper parts, as well as shafts, thin-walled pipes, turbines.etc.
Features:
- Accord to the Standard GB/T 34205-2017, DIN50159-1 and ASTM -A1038
- For materials with different elastic modulus. multi-point calibration function
- Support hot-swap and self calibration: automatically + by manual identifies the probe
- The material function include 3 new material settings to facilitate hardness testing of special materials
- 3.5-inch IPS (In-Plane Switching) full digital LCD display with wide viewing angle, and the back light can be adjusted arbitrarily. Display resolution 480×320.
- USB communication interface allows for data exchange with PC and settings 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
