Nanovolt Performance at a Microvolt Price

   The Agilent/HP 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.

Two Input Channels

   An integral two-channel programmable scanner simplifies voltage comparisons. Built-in ratio and difference functions enable auto mated 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.
