The Agilent HP Keysight U1273A is a 4.5-digit handheld digital multimeter delivering True RMS AC+DC measurements with 30,000-count resolution and exceptional accuracy for field service, maintenance, and laboratory troubleshooting. Its OLED display with 2000:1 contrast ratio and 160-degree viewing angle provides crisp readability in variable lighting. Built for reliability in harsh environments, the meter combines IP54 water and dust resistance with CAT III 1000 V and CAT IV 600 V overvoltage protection, while advanced measurement modes—including Low Pass Filter for VFD diagnostics, Low Input Impedance mode to suppress stray voltages, and Smart Ω function to eliminate leakage-current errors—solve real-world troubleshooting challenges.
