Extech EX430A 11-Function True RMS Professional Multimeter
The Extech EX430A is a professional-grade True RMS multimeter that blends a wide spectrum of measurement capabilities with solid field performance—covering voltage, current, resistance, capacitance, frequency, duty cycle, temperature and more—making it a reliable all-in-one tool for technicians, engineers and service personnel.
Description
The EX430A is designed to serve as a comprehensive diagnostic instrument for electrical professionals. Its True RMS measurement technology ensures accurate readings even when faced with distorted or non-sine-wave signals. The meter covers AC and DC voltages and currents up to 600 V and 10 A respectively, and it supports resistance up to 40 MΩ, capacitance up to 100 µF, frequency from 0.001 Hz to 10 MHz, duty cycle from 0.1 % to 99.9 %, and temperature measurement via a built-in Type K thermocouple input from -20 °C to 750 °C (-4 °F to 1382 °F) with fine resolution. The device features a large back-lit LCD display, ergonomic housing with protective holster and tilt stand suitable for field use, and is rated for CAT III 600 V safety. Autoranging functionality, relative mode, data hold, and built-in fuse protection and mis-connection warning make it secure and convenient in real-world applications. Whether inspecting industrial power systems, performing HVAC diagnostics, or servicing panels, the EX430A is engineered to deliver reliable performance with broad capability in a single handheld unit.
