DESCRIPTION

The DM66 is a True RMS digital multimeter designed for electrical and field service applications, combining precise measurements with robust construction. It features a comprehensive measurement suite including AC/DC voltage and current (up to 10 A), capacitance (200.0 nF to 10.00 mF), frequency counter (up to 50.00 kHz), temperature measurement via Type-K thermocouple (-40°C to 400.0°C), and low impedance (LoZ) mode to prevent ghost voltage errors. The meter offers a maximum voltage range of 600 V with accuracy ratings of ±1.0% for AC/DC volts and includes variable-frequency drive (VFD) mode, diode testing, continuity checking, and resistance measurement up to 6.000 MO. Built for durability with a 2 m drop test rating, IP40 protection, and CAT IV-300V/CAT III-600V safety certification, the DM66 is ideal for commercial electricians, automation field service technicians, and electronics repair professionals who require reliable, accurate diagnostics in demanding environments.
