New Product Upgrade: Four-Point Probe System

Posted on Fri, Nov 09, 2018 by Ashley Wong

The newly-upgraded Ossila Four-Point Probe System has officially launched!


If you are looking for a quick, accurate, and easy method for measuring the sheet resistances of various materials, this system is all that you need. This latest version is built on our new X200 Source Measure Unit.

Key Upgrades & Improvements

Sleek, durable casing: The system is now completely encased in a static-free metal casing, which protects the internal circuitry.

Current range capacity increased: The Four-Point Probe System is now capable of delivering a maximum current of 150 mA (compared to the previous maximum of 100 mA).

Measure even lower sheet resistances: Following on from the point above, the system is now able to detect smaller voltage changes. As a result, you can now measure sheet resistances as low as 3 mΩ/□ (compared to the previous minimum of 10 mΩ/□).

Software-controlled current ranges: For safety and convenience, the current range switches can be controlled using the included PC software - so there is no need for manual adjustment.

Even higher accuracy: Negative polarity measurements can now be performed using the PC software - enabling you to calculate the average sheet resistance between positive and negative currents. This eliminates any voltage offsets that may have occurred, hence increasing the accuracy of your measurements.
