Concentric ring probe for surface resistance measurement - Desco 222002

The Desco 222002 concentric ring probe measures the surface resistance of ESD materials such as table mats, flooring and packaging. Its two concentric contact rings match the standardised electrode geometry and, paired with a resistance meter, deliver repeatable point-to-point readings.

Benefits

• Standardised concentric ring geometry for comparable measurements
• Carbon-loaded contact pads with a probe resistance below 50 ohms
• Defined own weight for even contact pressure

Technical data

• Type: concentric ring probe
• Probe resistance with carbon-loaded pads: below 50 ohms
• Weight: 2.72 kg
• Prior Vermason item number: H107C

Application

For determining surface resistance on dissipative and conductive ESD surfaces during incoming inspection and qualification testing.

Standards and compliance

Suitable for testing to EN 61340-5-1 and ANSI/ESD STM11.11.
