Description
Some measurements need more digits than any bench meter can show. The Keysight 3458A digital multimeter resolves 8.5 digits and still reads up to 100,000 times per second. Lost in HCM lists it for rental and sale, so a metrology team can borrow it for a campaign or buy it for the long term.
Eight and a half digits, with real stability
Resolution only helps when the reading stays put. For that reason, the 3458A pairs its digits with a high-stability option, which gives a basic one-year DC voltage accuracy of 4 ppm. DC voltage transfer accuracy reaches 0.1 ppm. Auto-calibration also compensates internal gain and offset effects, so long measurements drift less.

Installed options can change the capability of a delivered unit. The quote and the serial-number configuration therefore settle the details.
Speed and memory for system work
Fast reading modes raise throughput on automated systems. Because the meter stores 148,000 readings, it can also log or digitize a low-noise signal for a long stretch. GPIB is the single interface, so plan the controller and cabling before the unit arrives.
Choosing it with care
A meter like this rewards good practice. Warm-up, cabling and a stable room matter as much as the digits. Therefore ask for the leads and adapters you need with the unit. Check that the options you want, such as the high-stability option, appear in the quote. The Keysight 3458A digital multimeter is also a system meter, so it needs a GPIB controller or adapter.
Where this meter earns its place
Precision DC voltage and resistance measurements are the core use. Calibration laboratories rely on such meters as transfer standards. Production test lines add it when they need both speed and accuracy. To start, request a quote from Lost in HCM and state the ranges, the options and the dates. The digital multimeter category shows similar meters, and you can read the Keysight website or contact SMK Vietnam.
