Extech MA435T 400A AC Clamp Meter with NCV Detector

Extech logo

The Extech MA435T is a compact 400A AC clamp meter that enables users to take measurements in tight spaces while offering an ample 30mm jaw opening to accommodate conductors up to 350 MCM. The MA435T also features True RMS for better accuracy when measuring distorted waveforms; a large four-digit readout and illuminated display that enhances viewing in poorly lit work areas; and a thumb-dial selector that facilitates convenient, one-handed operation.

Key Featuresof the Extech MA435T

The Extech MA435T’s multimeter functions include: AC/DC current, AC/DC voltage, resistance, capacitance, frequency, diode test, duty cycle, continuity, and thermocouple temperature. Also built into the MA435T is the non-contact voltage (NCV) detector. Eliminating the need for a separate tester, the NCV detector uses a red LED to alert users to the presence of voltage on live wires. Additional features include a backlit LCD display, data hold, auto power off and low battery indication.
