Bosch GLM 100-25 C vs GLM 150 C

What the camera helps you do

Both tools measure distances indoors and outdoors and calculate areas and volumes from readings. The camera viewfinder helps you aim when the red laser spot is difficult to see. It does not remove limits caused by lighting, target surfaces or distance. These are distance measures, rather than tools that project alignment lines.

The main specifications side by side

^{[1] [2] [3] [4] [5] [6]}

For both favourable specifications, measure from the front edge to a highly reflective target, such as a white-painted wall, in weak background light at 25°C. Add the distance-dependent ±0.05 mm/m to the base ±1.5 mm figure.

^{[1] [3]}

For the GLM 100-25 C’s unfavourable specification, its English manual uses the front edge, a highly reflective target, strong background light, 25°C and high altitude. The GLM 150 C’s unfavourable footnote specifies the front edge, high target reflectivity and strong background light, without separately repeating temperature or altitude. In each case, add ±0.15 mm/m to the base ±3.0 mm figure.

The 0.5 mm display increment is separate from measurement accuracy. Both offer incline measurement through 0°–360°; the ±0.2° angular accuracy applies at 25°C after calibration at 0° and 90°, with an additional ±0.01° per degree up to 45°. The GLM 150 C labels its accuracy typical. Follow the manual’s reference-surface and calibration instructions.

GLM 150 C questions

Bluetooth and app compatibility

Bosch’s GLM 100-25 C India page names MeasureOn, and the 2026 India catalogue also names MeasureOn for the GLM 150 C. Older GLM 150 C material still refers to Measuring Master and early mobile devices. Check your actual phone or tablet, operating system, GATT support and current app requirements before relying on wireless transfer.

Pair inside MeasureOn and select the correct tool serial number. Free and paid plans have different features, so check any cloud or export function you need. Bosch says old Measuring Master and PLR measure&go records do not transfer directly to MeasureOn; export older records as PDF if you need to retain them.

Using either model well

Both support room dimensions, areas, volumes, wall-area calculations, stake-out and indirect height or length measurements, plus a timer and fold-out stop pin. Prefer direct measurements where practical. Indirect calculations require the manual’s geometry and are generally less accurate. Choose the correct reference edge, stop pin or tripod centre before taking a reading.

^{[1] [3]}

Hold the tool still with the lens, laser outlet and camera clear. Allow it to acclimatise after temperature changes. Check distance, incline and viewfinder alignment regularly and after impacts. Glass, reflective or textured surfaces, sloping targets and temperature gradients can affect readings.

Both have IP54 dust-and-splash protection. Avoid drops and never immerse either tool. Replace the complete AA set together with correct polarity and matching manufacturer and capacity, and remove cells for prolonged storage.

Accessories and safety

Both manuals name BT 150 tripod 0601096B00 for the 1/4-inch mount, passive target plate 2607001391 and red laser-viewing glasses 1608M0005B. Match the exact article and interface before buying; these references do not establish what is included with the tool. Set the tripod reference when using a tripod. The viewing glasses aid visibility but do not protect against laser radiation.

Read the exact manual and keep the warning label legible. Never point the beam at people or animals or look into direct or reflected beams. If it reaches your eyes, close them and turn away. Switch off after use, do not leave an active tool unattended and supervise children. Avoid explosive environments. The GLM 100-25 C manual also warns against photographing people or animals and against damaged display glass.

Observe Bluetooth restrictions around medical devices, petrol stations, aircraft and blasting areas. Keep magnetic accessories away from implants as directed in the manual.
