Fluke 1AC II VoltAlert - Non-Contact Voltage Detector Pen CAT IV 1000V
Fluke
Why we love it
Easy and straightforward to operate.
Detects voltage without contact.
Includes a 2-year warranty.
Main Highlights
EASY TO USE: The portable VoltAlert AC non-contact voltage testers from Fluke are simple and straightforward to operate – just touch the tip to a terminal strip, outlet, or supply cable. When the tip glows red and the unit beeps, you know there's voltage present. The audible tone can also be switched off if silent operation is desired.
NON-CONTACT: Detects voltage without the need for metallic contact. Senses the steady state electrostatic field produced by AC voltage through insulation without requiring contact to the bare conductor. A red glow at the tip and a beeping noise (if not switched OFF) indicates the presence of voltage.
CAT IV 1000V AC VOLTAGE: Voltage detection of 200 to 1000 V ac, a wide range to suit a broad spectrum of residential, commercial and industrial needs. Electricians, maintenance, service, safety personnel, and homeowners can quickly test for energized circuits and defective grounds on the factory floor, in the shop, or at home.
VOLTBEAT TECHNOLOGY: With innovative VoltBeat technology and continuous self-test – so you always know it's working. VoltBeat is a self-test feature for visual confirmation of battery and system integrity, and power on. It provides a double-flash every two seconds during normal operation. The Fluke VoltAlert Tester automatically powers off to save battery life after 5 minutes of non-use. When the battery voltage drops below two volts, VoltBeat provides visual indication by stopping the VoltBeat flash.
BUY WITH CONFIDENCE: Since being founded in Connecticut, USA in 1948, Fluke has become the world leader in test and detection equipment trusted by professionals. Use the Fluke 1AC II if you need a quality tool for general voltage detection. Tester comes complete with 2 x AAA batteries installed and a 2 year warranty as standard.
