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.
