Bosch GLM 40 Laser Distance Measurer Range up to 40m

Measurement range: 0.15 m to 40.00 m. Typical accuracy: ±1.5 mm. Measurement time is typically under 0.5 seconds for a single distance.

The GLM 40 supports length, area, volume calculations, and indirect height measurements (Pythagoras) for vertical or angled situations.

It stores the last 10 measurements. The device features a three-line illuminated display, and it shows the last three measurements for quick reference.

It is built with IP54 dust and splash protection and a shockproof housing. It weighs about 0.09 kg, making it easy to carry on site and endure typical work environments.

The unit runs on two AAA (LR03) batteries. It includes an automatic shutoff feature after 5 minutes of inactivity to conserve energy.

Power on, align the laser with the target, press the measurement button to capture the distance, and read the result on the illuminated display. You can repeat measurements and use the memory to compare values later.

Indirect height measurement uses a baseline measurement and a second distance to calculate height via the Pythagorean theorem. This is useful for determining vertical dimensions when you can’t measure directly.

Avoid direct eye exposure to the laser beam and do not point it at people or pets. Use on appropriate surfaces and follow basic laser safety practices to prevent accidental reflections or misreads on very reflective or fragile surfaces.

The GLM 50 C generally offers a longer maximum range and may include additional features such as Bluetooth connectivity and a different display/readout. For specifics and to compare side-by-side, you can view the GLM 50 C listing on Fepy here: https://fepy.com/search?q=bosch+glm+50+c

The GLM 30 is typically a more entry-level model with a shorter range and fewer features than the GLM 40. For a direct comparison and current listings, you can view the GLM 30 listing on Fepy here: https://fepy.com/search?q=bosch+glm+30

Use a stable stance and keep the device steady while measuring, choose the appropriate measurement mode for the job (length, area, volume, or indirect height), take multiple readings and use memory to compare, replace batteries when performance declines, and keep the front lens clean for accurate readings.
