Take the Uncertainty Out of Low-Level Measurements

The Keysight 34420A nano-volt / micro-ohm meter is a high-sensitivity multimeter optimized for performing low-level measurements. This digital ohm meter combines low-noise voltage measurements with resistance and temperature functions. This new standard in low-level flexibility and performance provides you with accurate, repeatable measurements you can count on.

  • High sensitivity DCV and resistance measurements at 100 pico-volt and 100 nano-ohm
  • Accurate temperature measurements with 0.003˚C accuracy using standard platinum resistance thermometer (SPRT) probes
  • Built-in low noise 2 channel scanner simplifies voltage comparisons
  • Includes BenchVue software license, making it easier to connect, control instruments, and automate test sequences

Built-In Resistance and Temperature

The 34420A 7.5 digit multimeter combines its low-noise, nano-volt input circuits with a high-stability current source to provide precise low-level resistance measurements. This reduces the cost and complexity of using an external current source. Three resistance modes are included:

  • Standard
  • Low-power
  • Voltage-limited for dry-circuit testing

Offset compensation is also provided to minimize thermal electromotive forces (EMFs) and associated errors.
