The Keysight 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.
Two input channels
An integral two-channel programmable scanner simplifies voltage comparisons. Built-in ratio and difference functions enable automated two-channel measurements without the need for an external nanoVolt scanner. Both channels share the same low-noise specifications to ensure accurate comparisons.
Built-in resistance and temperature
The 34420A combines its low-noise nano-Volt input circuits with a high-stability current source to provide precise low-level resistance measurements – no more hassling with the cost and complexity of 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 EMFs and associated errors.
SPRT measurements
Built-in ITS-90 conversion routines accept the calibration coefficients from your SPRT probe for direct temperature measurement and conversion. Thermocouples, thermistors, and RTDs are also supported.
Unequaled versatility
The 34420A gives you the versatility to tackle your most challenging tasks, both on the benchtop and in your automated system. Standard features include RS-232 and GPIB interfaces, SCPI and Keithley 181 programming language, 1024-reading memory, scaling and statistics, and a chart recorder analog output.
Quality you can count on
The 34420A gives you the quality and reliability you expect from Keysight Technologies. From the Keysight proven > 150,000 hour Mean Time Between Failure to its standard 1-year warranty, Keysight stands behind you to bring a new level of confidence to your low-level measurements.
