The EX520A heavy duty true RMS industrial multimeter measures AC/DC voltage, current, resistance, and capacitance. It features dual sensitivity frequency (electric 1 kHz/electronic 10 MHz), a type K thermocouple -45°C to 760°C (-50°F to 1400°F), and a bead wire temperature probe -20°C to 250°C (-4°F to 482°F). It also features a 6000-count backlit LCD screen, 0.9% basic accuracy, relative/data hold, and an auto power function. With a CAT IV-600 V safety rating and an IP67 rating for water and dust, the EX520A is an ideal tool for electricians, HVAC technicians and benchtop technicians who require accuracy, durability, and safety in their electrical testing equipment.
