Extech MA445

Go to Product Support
product image

Three models to choose from, with or without True RMS and AC or AC/DC Current functions. Choose True RMS model for accurate readings of non-sinusoidal waveforms, model with DC Current function for automotive applications, or model with Type K function when applications require Temperature measurements. The MA440 Series meters are fully loaded with multimeter functions and built-in non-contact voltage (NCV) detector to meet your application needs!

  • True RMS Feature

    For accurate readings regardless of waveforms

  • Fully Loaded

    Functions include: NCV, AC/DC Voltage, AC/DC Current, Resistance, Capacitance, Frequency, Type-K Temperature, Diode Test, Continuity

  • Additional Features

    Relative mode for Capacitance, DC Zero and Offset Adjustment, Data Hold, Max/Min, Auto Power Off and Low Battery Indicator
