#1 in AC onlyFull review
An HVAC clamp with inrush, flame-sensor microamps and a CAT IV rating at a mid-range price.
Amazon $90.07$90.07
600 ANoCAT IV 600 V / CAT III 750 V
Under $150 buys a capable electrician’s clamp meter: true RMS readings, AC current, voltage, resistance and continuity, with a jaw wide enough for typical household and light commercial conductors. Many in this range add a non-contact voltage detector and a backlit display.
The corners that get cut are DC current measurement, temperature probes, inrush current and the highest safety category. Check the CAT rating against the panels and circuits you actually work on, and confirm the jaw fits your largest conductor. Auto-ranging, a data hold button and a sturdy case matter more day to day than a long feature list.
