In place of the traditional building tool come more and more advanced and efficient devices. The category of measuring devices in terms of technological progress is the most indicative. Developers create easy-to-use and accurate goniometers, thermal imagers and self-leveling devices. But the most popular and at the same time simple device in this line is the rangefinder. The Bosch DLE 40 Professional is an example of a highly accurate and ergonomic digital tape measure that can be used to measure from small construction sites to large industrial projects.
General information about the model
Despite the high demand for universal and multifunctional measuring instruments, the German manufacturer decided to follow the classical path and created a rather interesting rangefinder model. The device is positioned as a professional and this is the unusual approach. The fact is that the Bosch DLE 40 device has limitations in terms of range, but at the same time provides high accuracy in calculating distance and area. That is, on the one hand, the device can be considered as a household model, and on the other hand, it has enough capabilitiesfor professional use.
As for the limitations, the limit for measurements is noted in the name itself - up to 40 m. But the calculations are accompanied by a modest error of 1.5 mm. The Bosch DLE 40 laser rangefinder provides the final result in different metric systems, including meters, inches and feet. The body of the device is also interesting, which has a rubber coating that protects the electronic filling from damage. In general, the rangefinder is compact, equipped with raised buttons and a liquid crystal display.
Specifications
The main purpose of the device is to measure the distance from one object to another. Actually, the technical characteristics of the Bosch DLE 40, which are presented below, are focused on the qualitative implementation of this task:
- Number of reference points - 2.
- Measurement range - 40 m.
- Laser element class – 2.
- Error - 1.5 mm.
- Measures 100mm high x 58mm wide x 32mm deep.
- Weight - 180 grams.
- Wavelength - 635 nm.
- Powered by four 1.5V batteries.
If the rangefinder is selected specifically for professional tasks, then it should be borne in mind that the model is the youngest in the family of Bosch measuring equipment. This means not only a relatively modest maximum length measurement, but also the lack of additional features. For example, the electronic roulette in this modification is devoid of a built-in sight anddoes not include the function of rechecking the results.
Device Features
Like all Bosch tools, which are in some way at the junction of household lines and professional series, this model has absorbed the best qualities from both segments. For example, as it should be for high-end devices, the device received reliable external protection. The master can use the device in any conditions without fear that the slightest impact will adversely affect the accuracy of measurements.
The professional skills of the Bosch DLE 40 include a high speed of measurement. Depending on the complexity of the operation and, in particular, the distance, the time for data processing takes from 0.5 to 4 seconds. Again, the results presented will be highly accurate. At the same time, the model was developed taking into account the ergonomic needs of the modern builder. The device has a simple and convenient control interface, which allows you to successfully use the tool not only for specialists, but also for home masters.
Additional equipment Bosch DLE 40
As an addition, the company provides for the supply of the device with rechargeable batteries, means for charging them, tripods for convenient positioning of the laser and reflectors. The last accessory is of greatest interest to many. Reflective plates are used to extend the working range. Thanks to the equipment of such a component, an electronic roulette can perform calculations already several meters further and, whichmost importantly, do not depend on the quality of lighting. It is also worth noting the security features. Since the laser beam of the device can damage the retina of the eye, it is advisable to use special protective glasses during the working process.
Positive feedback about roulette
Basic performance gets a lot of rave reviews for the model. First of all, it is accuracy. Even against the background of other professional devices, the described rangefinder makes correct calculations regardless of the conditions of use. In addition, many users note the versatility that the Bosch DLE 40 laser tape measure demonstrates in solving various tasks. It has already been noted that the 40-meter distance for a professional device is an average value. But even models that work on 70 and 100 meters are not always able to maintain the same quality when processing results at small distances. According to the owners of this device, it effectively copes with the calculation of distances less than 10 m.
Negative reviews
In the first place in the list of shortcomings, you can still put a truncated functionality, but, again, when compared with the leaders of the segment. In particular, users complain about the lack of backlight and the lack of a sight. True, it is the absence of these additions that explains the modest dimensions and ease of handling of the Bosch DLE 40. The price of the model is about 7 thousand rubles. on the Russian market, which is also perplexing for many. Many Chinese devices costing about 3-4 thousand have similar capabilities in nominal value. But, on the other hand, it is still impossible to compare these proposals in terms of data accuracy and reliability with German products.
Conclusion
The model demonstrates a rare example when a manufacturer seeks to master a not very popular segment, offering a truly high-quality device with a narrow specialization. Balanced technical parameters make the Bosch DLE 40 laser rangefinder the best solution for builders and assemblers. The device can be used both indoors and outdoors. In the first case, the user can count on maintaining high accuracy even despite the nature of the calculations that is non-standard for a rangefinder - at a short distance. As for the natural environment of using the device (in the air), the accuracy of measurements is noted both in sunlight and in conditions of poor visibility. However, experienced builders do not recommend using rangefinders in conditions of severe frost or at high air temperatures.
