Gossen Metrawatt SONDE 1081 Triangular Probe for Floor Resistance Measurement

Measuring floor resistance in ESD-protected areas requires a probe that makes reliable contact with the surface. The Gossen Metrawatt SONDE 1081 triangular probe provides three defined contact points for accurate surface and volume resistance measurements according to DIN EN 1081 and IEC 61340-4-1.

Who is it for

ESD coordinators and test technicians who need to verify the resistance of floors and work surfaces in EPA zones, using compatible resistance meters such as the Gossen Metrawatt METRISO series.
