Keysight Technologies 34420A

The Keysight Technologies, Inc. 34420A nanoVolt/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. 

Take the uncertainty out of your low-level measurements Low-noise input amplifiers and a highly tuned input protection scheme bring reading noise down to 8 nVpp. Combine this with 71/2 digits of resolution, selectable analog and digital filtering, 2 ppm basic 24-hour dcV accuracy, and a shielded, copper pin connector and you’ve got accurate, repeatable measurements you can count on.

Key Features:

•  7½ digit resolution 
• 100 pV, 100 nΩ sensitivity 
• 1.3 nVrms, 8 nVpp noise performance 
• Built-in low noise 2 channel scanner 
• Direct SPRT, RTD, Thermistor, and Thermocouple measurements 
• BenchVue now inlcuded
