4-Point Probe [NPS Version]
4-point probe is a high accuracy probe for measurement of resistivity.
DC Four Point Probe systems is one of the most reliable methods for resistivity or sheet resistance measuring of conductive materials.
It is a well known fact among engineers that the quality of the probing apparatus greatly affects the probing accuracy.
Especially, durability is important during the measurement of semiconductor materials as well as the accuracy.
Our 4-point probe manufactured by skilled worker is universally acknowledged as a high accuracy probe, and now many enterprise use the device as standard.
Needle is made of low-conductivity metal and tip is made of high-durability metal. We ensure the accurate measurement of variety samples by conducting NPS's unique "Micro-edge contact" treatment. (IP, MT, SB, EP etc. for types of wafers )
We possesses a lot of experiences and solid accomplishments in this field.
high accuracy, hight durability, world standard instrument, quick repair, unique design, etc.
