Our Laser Distance Meter can measure up to 131 feet (40 meters) and has the ability to calculate area and volume simultaneously. It is ideal for projects which require a large area to be measured easily and accurately, such as wind blades, deck surfaces and fiberglass tanks. This measuring tool was designed for one handed operation and features a large backlit multi-line LCD display for easy viewing. It’s built-in Area and Volume formulas will aid in calculating your composite project needs. This The Laser Distance Meter will also retain the last 10 maximum and minimum readings in its memory. Our Laser Distance Meter is available with NIST certification. This is an assurance program that certifies that a laboratory, manufacturer or individual product is fully equipped to calibrate equipment to National Institute of Standards and Technology (NIST) standards.
