The DM66-NIST True RMS Electrical and Field Service Multimeter with NIST Calibration and VFD Mode combines a rich feature set, precise measurements, and quality construction into a tool of exceptional value. The meter is easy to use and built to last, offering long term stability for everyday use. The DM66-NIST offers the accuracy and range of measurement options that you need, whether you are a professional, or just need the right tool for a DIY project.
The DM66-NIST has the added benefit of low impedance (LoZ) mode to prevent ghost voltage from delivering false readings. It measures frequency, diode, capacitance, and temperature, for a comprehensive feature set ideal for commercial electricians, automation field service, or electronics repair technicians.
