Laser distance meter Bosch GLM 40 40 m Black Blue

The Bosch GLM 40 is a compact laser distance meter that combines multiple measurement modes in a single device. It measures distances from 0.15 m up to 40 m and supports units in metres, centimetres, feet and inches. The illuminated display shows the last three measurements and the instrument stores up to 10 measurements in memory. The housing is splash- and dust-protected and shockproof, designed to withstand drops from up to 1 metre. Its small size and light weight make it suitable for a range of indoor installation tasks.

Advantages

Aim the laser at the target point and press the measurement button to capture the value; results appear on the illuminated display and the last three are visible for quick reference. For area and volume, measure required sides sequentially following on-screen prompts. Use the memory function to recall up to 10 previous measurements. Replace the AAA batteries when display or measurement performance indicates low power.

Usage recommendations

For accurate results, aim at a flat, reflective surface where possible and keep the device steady while measuring. Avoid direct sunlight on the target area and ensure batteries have sufficient charge during prolonged use.
