Note: The Keysight micro-ohm meter 34420A has been redesigned to meet RoHS-compliance. The new, RoHS-compliant version is available from 1st June 2021. The redesigned 34420A provides the same product performance and specifications, and is 100% code compatible with the previous product versions.

Benefits of the Keysight 34420A Precision Multimeter for Nanovolt and Microohm Ranges

  • High-sensitivity multimeter for low-level measurements - nano-Volt, mikro-Ohm.
  • 7½ digit resolution.
  • GPIB and RS232.

Keysight 34420A Nano-Volt and Micro-Ohm Meter

The Keysight 34420A nano-Volt, micro-Ohm meter is a high-sensitivity multimeter optimized for performing low-level measurements. It combines low-noise voltage measurements with resistance and temperature functions, setting a new standard in low-level flexibility and performance.

  • 7½ digit resolution.
  • High sensitivity DCV and resistance measurements at 100 pV and 100 nΩ.
  • 1.3 nVRMS, 8 nVpp noise performance.
  • Built-in low noise 2 channel scanners.
  • Direct SPRT, RTD, thermistor, and thermocouple temperature measurements with 0.003°C accuracy.
  • 3 low power, dry circuit testing built-in resistance functions.
  • GPIB and RS232 interface.
