Laser distance meter Bosch GLM 50-27 C PROFESSIONAL

The Bosch GLM 50-27 C Professional laser distance meter is a compact, durable measuring tool designed for professional use. It measures distances from 0.05 m to 50 m with an accuracy of ±3 mm, supports multiple units (m, cm, mm, ft, in) and includes Bluetooth® connectivity for fast data transfer to the Bosch MeasureOn app. The device features an IP65-rated, shock-absorbing housing, a high‑quality colour display and user-friendly interface, and is powered by 2 AA batteries with an improved runtime compared to the predecessor model.

Advantages

The GLM 50-27 C combines robust protection against dust and water (IP65) and drop resistance from 1.5 m with intuitive operation via a colour display and help function. Bluetooth® connectivity enables quick documentation and transfer of measuring results to mobile devices using the MeasureOn app. Additional feedback through sound and vibration confirms successful measurements, and an auto power-off function after 5 minutes of inactivity helps conserve battery life.

Suitable for

• Architects and site planners for room and wall area calculations
• Electricians and installers for placing and fitting elements
• Contractors and builders for quick distance checks and material estimation
• Surveying and documentation tasks requiring digital transfer of measurements

How to use

Switch on the device and select the desired unit of measurement on the interface. Aim the laser at the target surface and press the measurement button; the distance value will appear on the colour display. Use the help function on the device for guidance on specific measurement modes. For documentation, pair the GLM 50-27 C with a smartphone via Bluetooth® and transfer results to the Bosch MeasureOn app. Replace batteries with 2 AA cells when the battery indicator is low.

Usage recommendations

For accurate results, ensure the target surface is reflective enough for the laser beam and avoid measuring through glass or transparent materials. Store the device in a dry, dust-free place when not in use and replace batteries before long measurement sessions to maintain the extended runtime.
