*Load (needle pressure) is always suitable since using V type spring *Probe spacing accuracy and probe stability is excellent since anodized aluminum alloy upper and lower guides are jeweled
*Less damage of probe needle tips - Solid tungsten carbide needles for superior durability

The probe type is chosen under the material of measuring sample, the surface state, the form etc.
