Since its founding in 1948, fluke has helped define and grow a unique technology market, providing testing and troubleshooting capabilities that have grown to mission critical status in manufacturing and service industries. From industrial electronic installation, maintenance and service, to precision measurement and quality control, fluke tools help keep business and industry around the globe up and running. As electrical systems grow more and more complex, spikes, transients, surges, and sudden over voltage events become more common. These can trigger a sequence of events that may lead to serious injury. This is why test equipment must be designed to protect people who work in this high-Voltage high-current environment. The next generation volt alert ac non-contact voltage testers from fluke are easy to use, and feature volt beat technology. Just touch the tip to a terminal strip, outlet, or supply cord. When the tip glows with a high intensity red led and the unit beeps, you know there's voltage present. It senses the steady state electrostatic ?eld produced by ac voltage through insulation without requiring contact to the bare conductor. Electricians, maintenance, service, safety personnel, and homeowners can quickly test for energized circuits in the workplace or at home. The fluke 1lac-a-ii low voltage detector is a category iv -1000-Volt over voltage rated product for added user protection, the highest rated of its kind. The tester meets 1000 v, cat iv safety rating. The 1lac-a-ii has an expanded range of 20 to 90-Volts ac and runs on two AAA alkaline batteries (included). The continuous self-test lets you know it's working. The fluke 1lac-a-ii has a round tip, is sold one item per package, and is covered by a two year warranty.
