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

The 421D, 416D and 411D laser distance meters offer:

Reduction of estimation errors, saving both time and money The most advanced laser technology for distance measurement Instant measurements of the distance between two objects with one-button operation Easy targeting with bright laser Measurement to 30 m (100 ft) with accuracy of 3 mm (0.12 in) Quick calculations of distance formulas such as area (square feet/meters) and volume Easy performance of distance addition and subtraction calculations Pythagoras function for indirect measurement via two other measurements Improved battery life from automatic shut-off feature Display holds for easier viewing in hard-to-reach areas Batteries: two AAA Carrying pouch to secure on tool belt Two-year warranty

The 421D and 416D additionally offers:

Ability to view more data with backlit, three-line display Ability to measure up to 60 m (200 ft) with increased accuracy of up to 1.5 mm (0.06 in) Full Pythagoras function (determine distance indirectly via two or three other measurements) Audible activation and shut down notification Storage of the last ten measurements for quick recall of distance Minimum and Maximum function Strong environmental protection with IP54 (water spray and dust proof) sealing

The 421D additionaly offers:

Ability to measure up to 100 m (330 ft) Storage of the last twenty measurements for quick recall of distance Audible feedback for taking room angle and incremental measurements ±45 ° Tilt sensor for taking indirect measurements in hard to reach areas Tripod mode allows you to mount to a tripod for measuring long distances Built in light sensor for activating the backlight saving battery life Corner angle feature, allows you to determine the angle of a corner

* 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).
