Bosch GLM 120 C vs GLM 40 - Where are the differences?
Where are the differences?
Let's take the two laser distance meters GLM 120 C and GLM 40 the Make Bosch in the comparison and look at the differences.
measuring range / distance
The measuring range of a laser rangefinder is extremely important. The number describes the maximum distance the device can measure. For most devices the maximum distance can be derived from the name.
With a maximum distance of 120,00 m the Bosch GLM 120 C offers more measuring range than the Bosch GLM 40 with 40,00 m. Theoretically, the larger measuring range is of course better. However, if you do not need so much distance, the smaller Bosch GLM 40 is also sufficient.
The minimum distance is the Bosch GLM 120 C at 120,00 m. The Bosch GLM 40 can determine a minimum distance of 40,00 m for the measuring range.
The indicated measuring range usually refers to ideal conditions. Poor weather conditions can affect the measuring range. This includes fog, for example. This is interesting for use on construction sites. In home use, this usually plays hardly any role. Under bad conditions the possible measuring range is smaller.
Measuring accuracy
The better a laser rangefinder is, the more accurate the results. The differences here are in the range of a few millimeters.
At the point of measurement accuracy both devices perform equally well with a maximum deviation of +/- 1,50 mm. Therefore, there is no difference at this point in the comparison. Therefore, there is no difference at this point in the comparison. In bad weather conditions, the measuring accuracy can be worse, just like in the measuring range.
Good rangefinders can output smaller steps in the measurement. Of course this also affects the accuracy of the measurement. The measurement results are output at the Bosch GLM 120 C in steps of 0,50 mm. Thus the device offers smaller steps than the GLM 40 of Bosch in comparison. There the smallest step is at 1,00 mm.
Measurement functions
Most devices offer even more than simple distance measurement. This includes area function, room function and summation.
In contrast to the Bosch GLM 40, the Bosch GLM 120 C offers an area function. You can have the area calculated directly at the measuring device.
One difference is the room function, which only offers you the Bosch GLM 120 C in this comparison. With the Bosch GLM 40 you have to determine the volume (m³) manually from your measured values. The danger of errors is greater here.
With 50 memory locations, the Bosch GLM 120 C offers you more storage possibilities for measured values than the Bosch GLM 40 with 10 memory locations.
Inclination measurement
You have a tilt measurement at the Bosch GLM 120 C. The Bosch GLM 40 does not offer this function. The tilt measurement allows you to determine angle sizes.
Accumulator and batteries
To save energy, both devices switch off automatically. The automatic switch-off time is 5 minutes for both measuring devices.
