LDM40
A compact 40-meter platform for standard-model selection, private label, and scoped OEM evaluation.
LDM40 Compact Laser Distance Meter
A Compact Platform for Portable Measurement
The LDM40 measures from 0.05 m to 40 m in a compact format. Two-button operation keeps standard distance measurement separate from functions such as area, volume, and indirect measurement. For brands and importers, it is a practical starting point for standard-model selection or a scoped OEM discussion.
Compact Format for Portable Use
At 83 g and 98 mm long by 36 mm wide, the LDM40 is easy to carry between rooms, sites, and work areas. Its compact platform supports product-range planning where portability and straightforward handling matter.

 | Hold the measurement button to use continuous mode while moving the device. The displayed maximum and minimum readings can support basic room or layout checks. |
 | In Area mode, measure the width and length and the device displays the calculated area. |
 | In Volume mode, measure width, length, and height; the device then displays the calculated volume. |
 | Indirect Measurement uses the on-screen sequence to calculate a height or gap from the listed measurements. Review the workflow and documentation when assessing the function. |
 | The unit setup lets users switch among the available measurement units. Confirm the supported units and regional presentation before publication. |
