  • 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 421D Laser Distance Meter does the work for you.

    The Fluke 421D is a professional-grade laser distance meter — it’s fast, easy to use, and fits on your tool belt. This meter 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

     

    The Fluke 421D Laser Distance Meter is better than an ultrasonic device because it uses laser light waves and measures their reflection to accurately determine distances:

    • Most advanced technology for measuring distances
    • More accurate and measure longer distances
    • Rugged and reliable as customers expect from Fluke products
    • Ability to view more data with backlit, three-line display
    • Ability to measure up to 100 m (330 ft)
    • Full Pythagoras function (determine distance indirectly via two or three other measurements)
    • Audible activation and shut down notification
    • Audible feedback for taking room angle and incremental measurements
    • Tripod mode allows you to mount to a tripod for measuring long distances
    • Storage of the last twenty measurements for quick recall of distance
    • Minimum and Maximum function
    • Strong environmental protection with IP54 (water spray and dust proof) sealing
    • ±45 ° Tilt sensor for taking indirect measurements in hard to reach areas
    • Built in light sensor for activating the backlight saving battery life
    • Corner angle feature, allows you to determine the angle of a corner
