Digital Clamp Meter -- ACA, ACV, DCV, Ohm, Diode, Buzzer.

The GCM-403 is digital clamp meter can measure AC/DC voltage, AC/DC current, resistance, diodes, continuity, capacitance, frequency and temperature.  Tapered jaws, auto range, data hold, REL function and auto power off which makes it a superb tool for electricians. 

The GCM-407 is digital clamp meter with true RMS measurement. Featuring tapered jaws, a wide range (AC 600A/750V, DC 1000V max input), capacitance measurement as well as non-contact voltage sensing function and the ability to keep MAX/MIN or hold data  and automatically power down make the GCM-407 suitable for almost any cable measurement task.

 

New Old Description
