Electricians, technicians, or experienced DIYers: the RETLUX RDM 8001 digital multimeter is designed to cover a wide range of measurements—DC and AC current, voltage, frequency, resistance, capacitance, diode testing, and non-contact NCV detection. Its automatic backlight activates in low-light environments, where tasks are often the most delicate. The built-in magnet on the back of the device allows it to be attached directly to an electrical panel or any metal surface, leaving both hands free to work. A versatile tool, designed for demanding usage conditions.
