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
• Download BenchVue Basic app for free to control your instruments
• Digits of Resolution: 7.5 digits
• Basic 1-Yr DCV Accuracy: 0.003%
• Measurement Functions: 2- and 4-wire Resistance, Temperature, DCV

Built-In Resistance and Temperature

The 34420A 7.5-digit multimeter combines low-noise, nano-Volt input circuits with a high-stability current source for precise low-level resistance measurements. This reduces the cost and complexity of using an external current source. 

It includes three resistance modes:

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

Offset compensation minimizes thermal electromotive forces (EMFs) and associated errors.
