  •  Fluke 421D 416D and 411D
    Want to determine the distance between two objects? Need to calculate area or volume? No need to learn how to read a tape measure or ruler, the Fluke Laser distance meters do the work for you.

    Fluke introduces a full line of Laser Distance Meters. The Fluke 421D, 416D and 411D are professional-grade laser distance meters — they’re fast, easy to use, and they fit on your tool belt. These meters will save you effort and money by reducing measurement time and errors!
    Use Fluke laser distance meters to quickly and accurately determine the distance to your target, the area bounded by two distances, or the volume within three measurements:

    • Reduce estimation errors, saving time and money
    • Instant measurements of the distance between two objects with one-button operation
    • Quick calculations of distance formulas such as area (square feet/meters) and volume
    • Easy performance of distance addition and subtraction calculations

    Laser distance meters are better than ultrasonic devices because they use laser light waves and measure their reflection to accurately determine distances:

    • Most advanced technology for measuring distances
    • More accurate and measure longer distances
    • Confidently measure up to 60 m (200 ft) with the 416D and 100 m (330 ft) with the 421D with an accuracy of 1.5 mm (1/16 in)
    • Rugged and reliable as customers expect from Fluke products

    Invaluable tool for every & any situation There is not anyplace that the Fluke 411D Laser Distance Meter does not come in handy. Originally purchased for use at work for measuring cable runs and such. The Fluke 411D can measure almost anything large or small. Inside dimensions, hard to reach spots are a specialty. After using it for only one week I ran out to my local Fluke distributor and purchased one for myself, and one as a present for a friend. June 7, 2012

    * In favorable conditions (optimal target surface, room temperature) up to 10 m (33 ft). In unfavorable conditions, such as intensive sunshine, very weakly reflecting target surface, or large temperature fluctuations, measuring accuracy may deteriorate to approx. ± 0.25 mm/m (± 0.003 in/ft) for distances above 10 m (33 ft).

    ** In favorable conditions (optimal target surface, room temperature) up to 10 m (33 ft). In unfavorable conditions, such as intensive sunshine, very weakly reflecting target surface, or large temperature fluctuations, the deviation over distances 10 m (33 ft) can increase by approx. ± 0.15 mm/m (± 0.0018 in/ft).
