Description
Tiny voltages and tiny resistances vanish under the noise of an ordinary meter. The Keysight 34420A nanovolt meter resolves 100 pV and 100 nΩ and shows 7.5 digits. Lost in HCM lists it for rental and sale. A research group can therefore borrow it for one study.
Reading very small signals
Its voltage and resistance functions pick out weak signals and tiny resistance changes. At this level, cables and contacts matter as much as the meter itself. Therefore, plan low-thermal leads and clean connections before the first reading. A quiet setup also makes your results easier to repeat. Note the leads, the warm-up time and the room with every result, so a colleague can run the same test later.

Two channels, a scanner and temperature input
A built-in low-noise scanner gives you two input channels. It makes voltage comparisons and ratio checks easy, because the pair needs no external switch. Temperature measurement works with standard platinum resistance thermometer probes. In addition, internal memory and GPIB or RS-232 ports help automated runs repeat.
Where low-level work happens
- Low-resistance contact and interconnect measurements.
- Thermometry and standards-laboratory comparisons.
- Sensor, materials and superconducting-device research.
- Low-noise voltage measurements and precision metrology.
Ordering the 34420A through Lost in HCM
Rent the Keysight 34420A nanovolt meter when a study has a fixed end date. Buy when the same low-level measurements return every quarter. Lifecycle status affects which units are available, so ask Lost in HCM what it can offer today. Then request a quote from Lost in HCM and itemize the leads, fixtures, scanner use and probes. Related meters sit in our digital multimeters category. The Keysight website has official documents, and you can also contact SMK Vietnam.
34420A questions answered
Which interfaces does it have?
GPIB and RS-232, according to the listing, so plan your cabling and software around them.
Can it measure temperature?
Yes, with standard platinum resistance thermometer probes. Probes and low-thermal leads need their own line in the quote.
How many input channels does it offer?
Two, through a built-in low-noise scanner that supports voltage comparisons and ratio measurements.
