MA445: 400A True RMS AC/DC Clamp Meter + NCV

Clamp Meter with Non-Contact Voltage Detector and Type K

View Datasheet > MA445


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!
