Product Details


Professional Distance Meter with auto correction & error report technology uses laser technology designed to give special users a high accuracy, one person distance, area and volume measurement precisely in an instant and estimating tool to measure remote and difficult reaching places. It can make use of Pythagorean Theorem to measure distances or lengths indirectly when direct measurement is not feasible.

Designed with many functions and features to make measuring easier including continuous measurement,addition/subtraction function and Max/Min measurement. Other main features includes 20 data memories, selectable metre, inch & feet units, backlight LCD with multi-line display and IP54 dust & splash proof.

A very useful tool for various types of applications in construction and industries and a very convenient to that gives accurate measurement of distance, area and volume especially in large areas such as rooms, apartments, buildings, real estates, factories, warehouses, gardens, roads, infrastructures, and many other applications requiring accurate results for distance , area and volume measurement.
