Fluke 411D, 416D, 421D laser distance meters use the most advanced distance measuring technology. These meters are fast, accurate, durable and easy to use; point and shoot one-handed operation. Their simple design and easy one-button operation means you spend less time measuring while increasing the reliability of the answers you need.

The compact and handy Fluke laser distance meters were designed for indoor and limited outdoor applications. With shortcut keys for addition, subtraction, area and volume, measurements could not be simpler. The meters also have a Pythagoras calculation function to determine distance indirectly, from two other measurements. The extra bright laser is clearly visible so you can always see your targeting point if the target object is in a hard-to-reach spot or a long distance away.

The Fluke 421D and 416D have a backlit, three-line display for improved visibility, enhanced Pythagoras calculations for determining distance indirectly form three other measurements, audible feedback of on and off modes, measurement storage for quick recall, min/max function and IP54 water-spray and dust-proof sealing.

Additionally the Fluke 421D has audible feedback for taking incremental measurements, ± 45° tilt sensor for taking indirect measurements in hard to reach areas, a built-in light sensor for activating the backlight and a corner angle feature to determine the angle of a corner. The Fluke 421D can also be mounted to a tripod for measuring long distances.

The Fluke 411D, 416D and 421D ship complete with:

  • (2) AAA batteries
  • User manual on CD
  • Quick start guide
  • Nylon carrying case
