Surface Resistance Testers
Surface resistance meters are used to evaluate and verify key elements of an ESD control program.
Surface Resistance Meters help support ESD audits and confirm whether ESD control materials meet required performance standards. A surface resistance meter measures the electrical resistance of materials and surfaces, making it useful for testing ESD mats, heel grounders, ESD apparel, work surfaces, flooring, and other items used in ESD-protected areas.By using surface resistance meters regularly, facilities can ensure that their ESD protection products continue to perform properly and help reduce the risk of static damage.
What Is an ESD Surface Resistance Meter?
An ESD surface resistance meter is an electrical test instrument used to evaluate the resistance characteristics of surfaces and materials used in an ESD control environment.
Static-control materials are designed to control how electrical charge is generated, accumulated or dissipated. Over time, contamination, wear, environmental conditions or changes in materials can affect their electrical properties.
Routine resistance testing can therefore help ESD personnel check the condition of materials such as:
- ESD table mats
- ESD work surfaces
- ESD flooring
- Storage surfaces
- Conductive or static-dissipative materials
- Other surfaces used in ESD-protected areas
The appropriate measurement method depends on the material being tested, the instrument configuration and the requirements of the facility’s ESD control program.
Surface Resistance vs. Surface Resistivity
Surface resistance and surface resistivity are related terms, but they should not automatically be treated as interchangeable.
Surface resistance describes a resistance measurement made between defined points or electrodes on a surface and is normally expressed in ohms (Ω).
Surface resistivity describes a material property determined using a defined electrode geometry and measurement method.
For this reason, buyers should check whether an instrument is designed to measure surface resistance, surface resistivity or both.
The SK-901 is presented as a surface resistance meter, with its resistance range specified in ohms.
If your application requires a specific surface resistivity measurement method, confirm the required electrode configuration, test method and instrument specifications before purchasing.
Frequently Asked Questions
What is an ESD surface resistance tester used for?
An ESD surface resistance tester is used to evaluate the electrical resistance characteristics of materials and surfaces used in static-control environments, including compatible ESD mats, work surfaces and flooring.
What is the difference between a surface resistance meter and a surface resistance checker?
A meter may provide a precise numerical resistance reading, while a checker may indicate an approximate resistance range or decade. The SK-901 uses LED range indication and is designed for quick routine resistance checks.
What resistance range does the SK-901 measure?
The specified measurement range of the SK-901 is 10³ Ω to 10¹² Ω.
