The Hioki P2010 DC High Voltage Probe is an accessory for use with the Hioki DT4261 Digital Multimeter or CM Series Clamp Meters. It enables high voltage measurement up to CAT III 2000V by simply connecting to a compatible Hioki Digital Multimeter or Clamp Meter. Photovoltaic power generation equipment are becoming increasingly high-voltage in order to reduce costs and improve the efficiency of power generation systems. As a result, it is important to select measuring instruments that support higher voltage measurement to protect the safety of inspection workers.
