Description
When a reference or a sensor drifts only a few parts per million, a 6.5-digit meter can blur the story. The Keysight 34470A digital multimeter adds a seventh digit and a digitizing mode for exactly that kind of job. Lost in HCM lists it for rental and sale, so a metrology group can borrow it or a lab can buy it.
Keysight 34470A digital multimeter: seven and a half digits
Keysight specifies 16 ppm basic one-year DC voltage accuracy for this model. It reads up to 50,000 times per second and stores 50,000 readings. Truevolt architecture also keeps results stable and repeatable on real signals, not just on clean lab sources.

Currents down to picoamps
However, many bench meters stop at milliamps. This one adds a 1 µA range with picoamp-level resolution. As a result, the Keysight 34470A digital multimeter can characterize leakage and standby draw in low-power devices.
Digitizing, triggering and trend views
The meter can digitize a signal and trigger on an event, so it captures short transients between slow readings. A 4.3-inch color display then shows trend, histogram and bar-chart views. In addition, front and rear inputs let you use it on a bench or inside a rack.
Typical work in Vietnam
- Precision voltage and resistance measurement.
- Low-current device characterization.
- Sensor stability studies.
- Production test and data logging.
- Extra capacity for a busy calibration lab.
Compare it before you choose
Common rivals are the Keithley DMM7510 and the Rohde & Schwarz HMC8012. However, compare them on your own test, not on one headline figure. Look at accuracy, digitizing rate, low-current ranges, memory and the way you plan to automate.
Rental or purchase
Rental suits a stability study or a lab that needs extra capacity for a few months. Purchase, in contrast, suits a team that measures at this level every week. Either way, Lost in HCM checks the available unit before it confirms anything.
Asking for a quote
Give the measurement range, the options you need, your delivery site and any certificate requirement. That way the quote covers the Keysight 34470A digital multimeter exactly as your lab needs it. Then request a quote from Lost in HCM. You can also compare other digital multimeters, visit keysight.com, or contact SMK Vietnam.
34470A questions
Can it measure very low current?
Yes. It includes a 1 µA range with picoamp-level resolution.
Does a rental include calibration?
Not automatically. Confirm the calibration status and certificate needs in the quote for the specific unit.
Which interfaces does it offer?
LAN and USB, with GPIB as an option.
