Bosch GLM 40

The Bosch GLM 40 Laser Measure, 40m Range, ±1.5mm Accuracy, IP54 provides a high-precision solution for distance, area, and volume calculations on active construction sites. This professional-grade tool features an ISO-certified measuring range of up to 40 meters and maintains consistent accuracy even in demanding environments.

Built for the Job

Contractors and site supervisors use this equipment to replace traditional tape measures for faster, one-person operation. The unit fits easily into a pocket or tool belt, making it accessible for quick checks of ceiling heights or room dimensions. Electricians and plumbers rely on the continuous measurement mode to find exact distances from walls or fixtures in real-time. This device handles the rough conditions of a shell-and-core build or a renovation project without failing. The internal memory stores the last ten measurements, allowing users to record data back at the office without needing a notepad on the ladder.

• Calculating floor areas for tiling, carpeting, or laminate installation in residential and commercial spaces.

• Estimating wall surface areas for paint, plaster, or cladding requirements to minimize material waste.

• Determining volume for HVAC system sizing or concrete pour requirements in small to medium rooms.
