Bosch GLM 120 C vs GLM 250VF - Where are the differences?

Let's take the two laser distance meters GLM 120 C and GLM 250VF 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 120,00 m the GLM 120 C from Bosch has a smaller measuring range than the Bosch GLM 250VF with 250,00 m. Thus the Bosch GLM 250VF is better. However, if you do not need such a large measuring range, you can choose the smaller Bosch GLM 120 C with less distance.

The minimum distance is the Bosch GLM 120 C at 120,00 m. The Bosch GLM 250VF can determine a minimum distance of 250,00 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.

For the GLM 250VF from Bosch the accuracy is worse with a maximum deviation of +/- 31,12 mm than for the GLM 120 C. There the accuracy is +/- 1,50 mm. The measuring accuracy refers to good conditions. If bad weather conditions are given, the measuring accuracy can deteriorate. The same is true for the measuring accuracy.

Good rangefinders can output smaller steps in the measurement. Of course this also affects the accuracy of the measurement. The smallest step at the Bosch GLM 120 C is 0,50 mm. With steps of 0,10 mm, the Bosch GLM 250VF offers the possibility of a better measurement.

Measurement functions

Most devices offer even more than simple distance measurement. This includes area function, room function and summation.

The area function is offered by both devices from the comparison. Here you can calculate the area from your measurements directly with the laser measuring device.

Both measuring devices from this comparison offer you a room function which allows you to determine volume (m³). Classically this function is used to determine a room size.

With 50 memory locations, the Bosch GLM 120 C offers you more storage possibilities for measured values than the Bosch GLM 250VF with 30 memory locations.

Inclination measurement

With the inclination measurement angles can be determined. This is not possible with every laser rangefinder. In this comparison both devices offer you an inclination measurement.

Both cover a range of 360 °. With 0,20 ° both offer the same at the minimum measurement unit. The accuracy of the inclination measurement is 0,10 ° for both.

Accumulator and batteries

To save energy, both devices switch off automatically. The automatic switch-off time is 5 minutes for both measuring devices.
