AGILENT TECHNOLOGIES U1273AX OLED handheld digital multimeter can operate in temperatures as low as -40C with no warm-up time required. While exceling in the wintertime, unit remains useful throughout the year with an operating temperature range that extends up to 55C. Coupling this range with IP54 water and dust resistance, plus a CAT IV/600 V safety rating, creates a robust tool that will help users keep their operations running smoothly. Device presents 4½-digit resolution on an OLED display that provides crystal-clear readings with a 2000-to-1 contrast ratio and 160-degree viewing angle. Advanced capabilities include a low-impedance mode that reduces ghost voltages from capacitive coupling, and a low-pass filter that eliminates switching noise from motor-drive measurements.
