The LDM-100A is a long-range 100m laser distance meter built for demanding measurement tasks in construction, engineering, installation, and facility management. Its 0.05m to 100m measuring range allows users to cover larger rooms, buildings, warehouses, and work areas with fewer repositioning steps.
With ±2.0mm accuracy, the LDM-100A supports distance, area, volume, Pythagorean, and angle measurement. Continuous tracking, maximum/minimum measurement, and addition/subtraction functions help professionals complete on-site calculations more efficiently.
The integrated memory stores up to 99 groups of measurement data for later review. A bright HD self-luminous LCD provides clear results, while metric and imperial unit options support different project requirements. Despite its 100m range, the meter weighs only 80g and features a compact soft-grip housing for convenient carrying and operation.
