About the SRM Probe

The SRM probe is a lower cost plastic bodied probe that is suitable for use in measuring a wide range of materials including various conductive coatings, ITO on glass, silicon wafers, ingots, potscrap, conductive paints, and various thin films. The connection to the probe head is made via a female RJ45 connector which is the same type of connector used for Ethernet connections.

Holding a probe head by hand does not always work well when measuring higher re-sistance materials and films, however, for many materials it is suitable.

The SRM probe heads are available in three choices of tip spacing, three choices of spring load, two choices of tip material, and three choices of tip radii.

ResTest Four Point Probe Measurement Unit

ResTest Four Point Probe Measurement Unit

The ResTest is a combined constant current source and digital voltmeter, which has been designed specifically for use with a four point probe to produce resistivity and sheet resistance measurements. The unit supplies a constant current and can display resultant voltage sheet resistance and volume resistivity.

The ResTest has a large color display and it can read-out in either sheet resistance in the range from 10 milliohms-per-square up to 106 (1 million) ohms-per-square. The range is not as great as the RM3000, however, it is faster and has a larger color display.
