MA440 Series 400A
Clamp Meters + NCV
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 Temperture measurements.
The MA440 Series pocket-sized meters are fully loaded
with multimeter functions and built-in non-contact
voltage (NCV) detector to meet your application needs!
