IDEAL 61-763 TRMS clamp meter measures up to 660A AC and 660A DC. Includes capacitance and frequency and incorporates the unique TightSight® bottom display making hard-to-reach measurements convenient
IDEAL 61-704 is four tools in one - TRMS Multimeter/Clamp, Non-contact voltage tester, voltage tester with shaker and harmonics tester
IDEAL 61-775 1000A AC and 1000A DC TightSight Clamp Meter with True RMS, Capacitance and Frequency
Compared to other ground resistance testers with 3 or 4 ground probes, there is no contest. Forget the probes, just clamp the meter around a service ground and you get an instant reading. Even better, the clamp tester reads the resistance of all parallel paths at once, instead of the single path measured with probes.
