Angled Probes for the BT500 Series Battery Analyzer

Make measurements without getting tangled! Angled tips get into narrow cabinet spaces while being just as robust to meet drop test standards. The angled probe continues the Fluke tradition of keeping you safe on the job at a CAT II 1000V and CAT III 600V rating. The BT520ANG and BT521ANG has everything the original BT520 and BT521 including the straight and angled probes. Complete your battery maintenance routine with new angled probes and extenders to get a reliable connection every time with minimal effort, saving you time.
