Voltage detector for 20–90 V AC

This non-contact detector identifies alternating current from 20 to 90 volts with an audible alert and visual indicator. It suits electricians and technicians who need a fast go/no-go check on live conductors without direct contact.

Sustained detection performance

Continuous self-test runs while the unit is powered on, confirming circuit readiness during extended use. The probe tip maintains consistent sensitivity across the stated range so repeated measurements stay reliable over long shifts.

Thermals noise and power draw

Battery operation keeps the tool silent apart from the intentional voltage alert tone. No display or backlight means negligible current draw, and the CAT IV 1000 V rating ensures safe insulation during normal field work.

Questions about this item

How much power does the Fluke FLK-1LAC-A-II draw when it runs continuously all day?

The detector uses a battery and includes an on/off button with continuous self-test that helps prolong battery life during extended use.

What must I already own for the Fluke FLK-1LAC-A-II to work out of the box?

It operates on a battery power source; ensure a compatible battery is installed before first use.

Will the Fluke FLK-1LAC-A-II safely check circuits on older panels rated below 1000 V CAT IV?

Yes, it carries a CAT IV 1000 V safety rating and detects AC voltage from 20 to 90 V, suitable for legacy installations within that range.
