EXTECH EX355NIST Digital Multimeter

The Extech EX355-NIST is a professional digital multimeter with ISO certification, offering precise AC/DC voltage, current, resistance, and frequency measurements. It features True RMS for accurate readings of distorted waveforms, a Type K thermocouple input for temperature measurement, and a built-in non-contact voltage detector with LED indicator for safety. Low Impedance (LoZ) technology eliminates ghost voltages, while the Low Pass Filter (LPF) reduces noise from variable frequency drives. The device has a 6,000-count backlit LCD, data hold, Min/Max functions, Auto Power Off, and is rated CAT III 600V, making it suitable for a wide range of electrical testing applications.
