Mini Clamp Meters + NCV
Model MA140
AC Current
Model MA145
AC/DC Current
Choice of AC Current or AC/DC Current model with 0.8" (22mm) jaw size and high accuracy. Smart Auto Sense feature enables
the MA145 to recognize the input (within a given function) and automatically switch to the correct mode of operation (i.e. AC to
DC Current measurement). Built-in Non-Contact Voltage (NCV) Detector allows for quick detection of live voltage.
