Digital Multimeters Catalog

The Keysight Digital Multimeters Catalog provides a comprehensive overview of benchtop, portable, and modular digital multimeters designed for product characterization, troubleshooting, maintenance, and precision measurement across engineering environments. Organized into Essential, Advanced, and Pro performance grades, the catalog covers five capability classes that span resolution from 5.5 digits to 8.5 digits. It includes general-purpose benchtop DMMs for education labs and everyday design and validation tasks, high performance benchtop DMMs for metrology-grade accuracy and precise measurements, portable handheld DMMs for field diagnostics, and modular PXI / PXIe DMMs for high density automated test systems. These digital multimeters enable you to characterize and debug devices, perform design validation, monitor key interfaces of subsystems during design, and ensure your products are properly tested to meet specifications.
 

Explore the three benchtop digital multimeter performance grades:

• Essential digital multimeters come in one class, the DM5-class, and include the EDU34450A and 34450A. Essential DMMs are affordable, entry-level, and ideal for an education lab. It features a large 7-inch, dual-measurement color display for easy viewing and simultaneous output monitoring. With 5.5 digits of resolution, our Essential DMM measures a broad range of signals, including DC voltage, DC current, true root mean square (RMS) AC voltage, AC current, two- and four-wire resistance, frequency, continuity, diode test, temperature, and capacitance. It comes with remote control and data logging software for real-time monitoring, capturing, and visualization crucial for testing and validation of your applications. It also captures fast-changing signals with enhanced input trigger settings and up to 5,000 samples in memory for post-analysis.
  
  
• Advanced digital multimeters come in two classes. The DM6-class includes the 34460A-34465A and DM34460A-DM34461A, and the DM7-class includes the 34470A. Advanced DMMs go beyond our Essential models, offering 6.5- and 7.5-digit resolution for enhanced accuracy, reduced noise, and minimized measurement errors. These DMMs feature improved triggering and digitizing capabilities, with a sampling rate of up to 50k samples per second to measure fast-changing signals like a clock pulse in a high-frequency circuit or an unwanted transient noise signal. A fast reading rate provides real-time measurements to detect voltage fluctuations, unstable signals, or current irregularities, indicators of faults or performance problems. Analyze dynamic current consumption of low-power devices with 1 microamp range and picoamp resolution. Advanced DMMs also self-calibrate regularly to reduce errors due to temperature and internal drifts, ensuring accuracy for long-duration characterization tests.
  
  
• Pro digital multimeters come in one class, the DM8-class, and include the 3458A. Pro DMMs deliver 8.5-digit precision, exceptional DC voltage (DCV) linearity, and minimal internal noise. With a sampling rate twice that of our Advanced DMMs, it captures up to 100,000 readings per second, making it well-suited for high-throughput manufacturing environments. Its supports high-resolution digitizing by providing 24-bit digitizer resolution, 12 MHz bandwidth, and a sample rate of 100,000 samples per second. Its metrology-grade accuracy ensures precise measurements, making it an ideal choice as a metrology standard in calibration labs, research labs, and demanding applications like power electronics, switching power supplies, and semiconductor testing.
   

Portable digital multimeters come in one class, the DM4-class, and include the U1200 Handheld DMMs. Portable DMMs are designed to withstand harsh working conditions, improve safety, and offer convenience in the palm of your hand, whether you are troubleshooting electronics or performing machinery installation and maintenance. Equipped with 800 hours of battery life, smart features like an integrated frequency counter and overvoltage protection, and data logging capabilities, our portable DMMs help you quickly detect issues and obtain accurate measurements in the field.
 

Modular digital multimeters offer the power of a benchtop DMM in a compact, flexible form factor, saving valuable rack space. Our top modular DMMs deliver equivalent DCV accuracy and faster reading rates than our Advanced models, all within high-density PXI / PXIe modules.
 

The catalog also highlights software and accessories that extend the capability of Keysight digital multimeters. DMM software supports instrument control, remote connectivity, automation, and lab management. Accessories include test probe leads, alligator clips, temperature sensors and probes, probe adapters, SMT grabbers, PC connectivity cables, fine tip probes, and protective cases to support accurate measurement across a wide range of applications.
