Extech EX330 12-Function Mini Multimeter with Non-Contact Voltage Detector
The Extech EX330 is a compact, autoranging 12-function multimeter that brings professional-level measurement capabilities into a portable form. Equipped with True RMS-like accuracy and a built-in non-contact AC voltage detector, it is designed for technicians needing diverse functionality in one device.
Description
The EX330 delivers a broad measurement suite including AC/DC voltage and current, resistance, capacitance, frequency, duty cycle, diode/continuity, and temperature via a Type-K thermocouple input. Its non-contact voltage detector senses live AC voltage from approximately 100 V to 600 V without the need for direct connection—offering a safer preliminary check. With a 4,000-count LCD display and autoranging capability, it simplifies measurements while maintaining resolution. The unit handles up to 10 A in current mode, 600 V in voltage mode, resistance to 40 MΩ, capacitance up to 200 µF, and frequency up to 10 MHz. It also supports temperature measurement from approximately -20 °C to 750 °C (-4 °F to 1382 °F). Additional convenience features include data hold, relative mode, max hold, a tilt stand and protective holster for field use. Safety ratings of at least CAT III 600 V make this meter suitable for industrial and service environments. In short, the EX330 combines versatility, portability and strong feature-set in one handheld tool for inspection and diagnostics tasks.
