The Agilent/Keysight Technologies 34420A 7 1/2-Digit NanoVolt/Micro-Ohm Meter, Refurbished 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. This model does not include accessories.

Take The Uncertainty Out Of Low-Level Measurements

Low-noise input amplifiers and a highly tuned input protection scheme bring reading noise down to 8 nVpp. Combine this with 7 1/2 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.

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.

Keysight IntuiLink: Easy Data Access

The included Keysight IntuiLink software allows your captured data to be put to work easily, using PC applications such as Microsoft Excel or Word to analyze, interpret, display, print, and document the data you get from the 34420A. You can specify the meter setup and take a single reading or log data to the Excel spreadsheet in specified time intervals. To find out more about IntuiLink visit www.keysight.com/find/intuilink.
