Check that your material and work surfaces won’t discharge static electricity, which can damage sensitive electronics. These testers are designed to take measurements in accordance with ANSI guidelines for electrostatic discharge control. They measure electrical resistance up to 1×10¹² ohms—five orders of magnitude greater than our multimeters.

These testers measure resistance between two points on a surface and from the surface to a ground. To avoid a sudden release of static, resistance should be between 1×10⁶ and 1×10⁹ ohms.

Use the small parts probe (sold separately) to measure resistance on small items or in hard-to-access areas. Use the packaging probe (sold separately) to measure resistance of thin packaging and films.
