Mini DC/AC Clamp Meters
Ideal for low current measurements
Extech’s Mini Clamp Meters, with their high resolution, are the ideal tools for
accurately measuring very low AC & DC currents. Smaller in size than traditional
clamp meters, they easily fit into tight spaces.
Features:
• Three models provide high Accuracy and Resolution
380942
• Large 4000 count LCD display with full function indication
• Fast 40 segment analog bargraph
• One touch "Auto Zero" for DCA measurements eliminates
the need to turn a knob to zero adjust
• Measure current draw when conducting energy usage audits
• Data hold, Max/Min recall display
380941
• 0.9" (23mm) clamp jaw opening
• Overload protection to 400A DC
• True RMS models recommended for measurements
where distortion may otherwise cause inaccuracies
• Optional 3-prong AC Line Separator enables safe
and easy measurements on power cables with
molded plugs (splits hot conductor from neutral
and ground)
