Currently, a change in conventional measuring instruments – rules, roulettes and t. D. Laser meters came (rangefinders). These are compact and convenient devices that do not require special skills to use them. This article talks about the instruments of the production of the Chinese company ADA INSTRUMENTS.
Appointment and principle of operation
Laser rangefinders are intended for remote measurement of distances. This is an indispensable tool when conducting construction and repair, designer, geodesic calculations, and T. NS. These devices, depending on the principle of operation, are divided into phase and impulse. The first type of device works like this: For a short time, the object with different modulation of the radiation frequency is highlighted and the phase shift indicator is calculated. They do not provide a returned timer of the reflected light signal, so the cost of them is lower, but also the range of measurements is less (about 1000 m). Used mainly in everyday life or as small sightsets.
Pulse laser rangefinders consist of a pulse source of laser radiation and detector. Determine the distance to the object by measuring the time spent by the light beam on the path to the object and back. Different with high ranges of measurements and are often used in military equipment.
Characteristics of models
ADA laser rangefinder software also includes a set of computing functions. The standard set includes the functions of determining the area, the volume of the objects of the objects, as well as indirect calculations on the Pythagore Theorem. The body of all models is made of impact-resistant plastic with rubber lining for a comfortable gripping hand, which also provides the protection of the IP54 class from entering the dust and moisture instrument. Many rangefinders are also equipped with tracking function – continuous measurement.

The data in the table is familiarized in the table, the manufacturer at any time may decide to change the parameters, modifications or product configuration. As can be seen from the summary data, the ADA models have no significant differences between themselves, mainly changes relate to the measurement distance. The MINI ruler of measurements are slightly higher than that of Cosmo and Robot, but all models are characterized by high measurement accuracy – error (maximum 3 mm) relative to the measured distance is ten thousand percent.
When choosing a suitable model, focus on the site of this instrument: for household purposes, for example, repair work in your own house you will have enough and devices with a maximum measurement range of 30 – 40 m. If you are a professional builder, then it is worth upset on the ADA COSMO 150 VIDEO A00475 model.
Operating recommendations
Contact the device carefully, do not drop, throw it or hit hard surfaces. Although it is protected from moisture impact, you should not bathe it or leave it on a vibrating surface. Observe the recommended device utilization ranges, you should not expose the device with high temperatures or aggressive external environment (it usually concerns the content of explosive substances in the air).
Do not blind the beam of coherent radiation neither, nor other living beings. Although the laser power is small, it can harm the retina. Independent opening of the device and its modification or repair with your own hands, as is the erase of index / warning inscriptions – all this will deprive you warranty service in case of faults.
When operating the device, a manifestation of the following problems may be:
- deformation of the hull;
- The device does not respond to pressing the power button;
- complete absence either partial decrease in the brightness of the source of the laser;
- Litted plane.
When you are detected, trust the setting and repair by qualified specialists.
