Outline
This machine is used for weld quality judgment, hardness judgment, material discrimination, and hardening depth judgment of steel materials.
hardness, material identification, and hardening depth determination of steel materials.
The 4-needle sensor only needs to touch the sample for 0.5 seconds,
The hardening depth can be determined up to 3mm.
The inspected product can be used as it is.
Please make use of it for quality control.
After hardening, the hardness of steel increases, and at the same time, the resistance value also increases.
By applying the potentiometric method and capturing this resistance value, the hardening depth can be calculated.
