Agilent/Keysight U1273A Handheld Digital Multimeter OLED

The Agilent/Keysight U1273A is a rugged, handheld digital multimeter designed for demanding industrial applications. It features a 4 ½ digit, 30,000-count OLED display that offers high contrast and wide viewing angles, even in low-light conditions. The multimeter is IP54 certified, indicating resistance to water and dust, making it suitable for harsh working environments. It operates across a wide temperature range, with specific models (U1273AX) capable of functioning down to -40°C, while others operate to -20°C. The device is safety rated for CAT III 1000V and CAT IV 600V.
