FLUKE T6-1000 Electrical Tester with Fieldsense (TM) Flat Apac T6-1000/APAC 1pc

Be safer: Measure voltage to 1000 V ac through the open fork, without test leads.
Be faster: No need to open covers or remove wire nuts.
Be more efficient: Simultaneously measure voltage and current.
Be everywhere: 17.8 mm open fork is widest in the industry; measure up to 200 A on 4/0 wires (120 mm2).
Go beyond simple detection. Actually measure ac voltage and current values without test leads.
