Fluke 1LAC-A-II Low Voltage Detector 20-90 VAC

The Fluke 1LAC-A-II is a pocket sized, pen style non-contact voltage detector for quickly identifying energised circuits in home or workplace environments. It senses the steady state electrostatic field produced by AC voltage through insulation without requiring metallic contact. The tip glows red and an optional beep sounds when voltage is present. It detects 20 to 90 VAC and carries a 1000V Category IV safety rating.

Electricians and maintenance staff checking low

This tool suits electricians and maintenance personnel who need rapid go/no-go indication on circuits between 20 and 90 VAC. It is not for users who must measure exact voltage values or verify the absence of voltage on conductors above 90 VAC. Buyers requiring a quantitative reading or a higher detection range should look at a different instrument. The detector weighs .0225 kilograms and measures 10.43 L x 7.5 W x 1.38 H inches.

20 to 90 VAC detection range

The single specification that decides suitability is the 20 to 90 VAC detection window combined with a 1000V Category IV rating meeting IEC 61010 1:2001, UL 61010 1, CAN/CSA C22.2 No. 61010 1 04 and ISA 82.02.01 Pollution Degree 2. If the application involves voltages outside this 20 to 90 VAC band, this detector will not indicate their presence. Continuous self test and Volt beats technology support reliable operation.

Questions about this item

How often will the alkaline batteries need replacing with daily use?

The detector runs on alkaline cells; replace them when the red LED dims or the beeper fails to sound during a known live circuit.

What stops the detector from working continuously during a long shift?

Battery depletion ends operation; the unit has no thermal shutdown and draws negligible current while idle.

Does the beeper and LED make the tool noisy or hot after hours of scanning panels?

The beeper is a brief audible chirp and the tip LED is a low-power red glow; neither generates noticeable heat or sustained noise.
