Extech 380950 80A Mini AC/DC Clamp Meter
The Extech 380950 is a mini clamp meter capable of measuring both AC and DC currents up to 80 A. Its extra-small jaw and compact form make it well suited for tight spaces. It also offers voltage, resistance, frequency, capacitance, duty cycle, continuity, and diode measurement functions, making it a versatile multi-tester for electricians and technicians.
Description
The 380950 is designed to access cramped places where full-size clamp meters struggle. It features an extra-small diameter jaw (approximately 0.5 in / 12.7 mm) which enables measurement in narrow cable runs. Despite its compact size, it offers 1 mA resolution in current measurement and supports both AC and DC modes. Alongside current, it functions as a full digital multimeter: you can measure AC/DC voltage up to 600 V, resistance, capacitance, frequency, and duty cycle, and it has diode test and continuity features. It uses a 4000-count LCD display to show readings clearly. The meter is powered by two AAA batteries and comes with test leads and a carrying case. Its safety rating is CAT III 300 V, and it’s ideal for field, HVAC, telecom, automotive, and general electrical diagnostics.
