Concentric Ring Probe Model 880 with Carrying Case and Calibration Certificate - Warmbier 7220.880.SET

The Warmbier Model 880 ring probe is a concentric measuring electrode for determining surface and volume resistance on planar ESD materials. Combined with a resistance meter it captures point-to-point, surface and resistance-to-ground readings in line with DIN EN 61340-2-3.

Benefits

• Conductive contact rubber (R < 5 Ohm) with silver particles for repeatable contact
• Total electrode resistance R < 30 Ohm
• Standard weight 2.5 kg, reached with a separate add-on weight (e.g. electrode Model 850)
• Complete set in a conductive carrying case with factory calibration certificate

Application

For measuring the volume resistance of planar materials and for resistance testing of ESD packaging, shielding bags and other flat materials within an ESD control program.

Standards and compliance

• DIN EN 61340-2-3
• IEC 61340-5-1
