During construction, it is important to accurately measure the distance between objects. Ultrasonic rangefinders are a great help in this. These devices are able to quickly measure the area. Many models are equipped with a chip that allows you to remember and process data. Devices among themselves differ in the accuracy of measurements and the functional part.
Ultrasonic Rangefinder: Instructions for Use
To use the rangefinder, batteries are installed, and to start work, you must press the power button. Next, the user must select a function for the device. If you are engaged in measuring distance, you should pay attention to the units of measurement. In the model settings there is an option to save data. When calculating the area, it is worth specifying the values. To reset the data, turn off the rangefinder.
When measuring the distance from the wall, it is necessary to install the device strictly perpendicular to the surface. When working with the device, you should pay attention to the permissible humidity and temperature parameters, otherwise the device may not work or show inaccurate data.
What is important when choosing
During repair work, high accuracy and compactness are greatly appreciated. The optimum measured distance is 20 meters. Batteries for the rangefinder, as a rule, are selected by the AAA series. Many devices have a minimum and maximum function. Thus, you can quickly calculate the data.
Information on the screen should be clearly visible. It is worth paying attention to operating conditions. So, a quality range finder is able to work at a temperature of -10 ° C. The operating humidity of the equipment is approximately 55%.
Inexpensive Rangefinders
There are many inexpensive rangefinders on the market that are made with low power lasers. Their maximum range is 30 meters, and the accuracy of the testimony fluctuates around 94%. Many of these devices are equipped with high-quality sensors. In addition, the models are able to work in an economical mode. Batteries are usually installed in a small capacity. The named devices differ in temperature conditions, and their average working humidity is 55%.
The HC SR04 standard ultrasonic rangefinder is capable of storing about 20 values. Also, models have the option of calculating data. The batteries in the rangefinders are used in the AA series. It is also worth noting that in stores the user is able to find devices with the option of voice signals. Judging by the reviews, such models are not bad for construction work.
Professional devices
Professional devices stand out for their long range. They set high-quality transmitters. At the same time, the chips are capable of storing more than 50 values. Some modifications work at low temperatures. The accuracy of determining the values is about 98%. If we consider the Arduino (ultrasonic rangefinder), then it has a working humidity of approximately 50%. Screens in devices are installed with high resolution and equipped with backlight.
You also need to remember that models are able to quickly calculate the area. They have a small diameter laser dot. For carrying out repairs on large construction sites, devices are great. The maximum permissible temperature of professional rangefinders is about 55 degrees.
15 meter devices
Devices with a range of 15 m, according to experts, are well suited for construction work in the apartment, but have some drawbacks. These modifications are usually equipped with small chips that are capable of storing no more than 20 values. In addition, these devices are poorly suited for indirect calculations. It is also worth noting that such models rarely have a minimum and maximum function. Screens are made with a small resolution. And many modifications work only at positive temperature. Their case is almost always protected from dust, but the models differ in terms of working humidity.
20 meter models
Rangefinders of 20 meters have recently been very popular and have good reviews. Many modifications are made with high-power lasers, but their points differ in diameter. Modern devices (such as the Arduino ultrasonic rangefinder) are well suited for small construction sites.
Named range meters vary in battery capacity. Some of them are equipped with a minimum and maximum function. These devices are rarely used for indirect calculations by the Pythagorean theorem. It is also worth noting that the chips in them are on average designed to store 30 values. The devices have different screens. And some modifications are able to boast of high-quality highlights.
Bosch PLR 25 model reviews
The specified ultrasonic rangefinder reviews, as a rule, receives a positive character. Modification has a lot of advantages, and among them the presence of compact sizes can be noted.
The case in the device is protected from dust, and the laser is used in the second class. Some customers praise the rangefinder for its high accuracy. The chip in the device is capable of storing a lot of data. Pretty quickly connected and connecting an ultrasonic rangefinder. Among the features it is worth noting the presence of the minimum and maximum options. The device may be used at sub-zero temperatures. You can buy this device on the market for just 5388 rubles.
Bosch PLR 15 model reviews
The specified range finder is often used during repair work. The case is well protected in the device, and it can work at high temperatures. At the same time, the range meter is not afraid of dust and dirt. The batteries he uses are AAA series. It is also worth noting that the model is great for calculating data over a long distance.
If we talk about the cons, then users note a long inclusion of the device. He uses a weak battery, and the model is not able to store a lot of data. It is also worth noting that the rangefinder does not have the option of minimum and maximum. The diameter of the laser dot is 5 mm. The device may be operated even at a temperature of 45 degrees. You can buy it at a price of 3588 rubles.
Dexter Ultrasound Devices
This company mainly produces range finders for professional builders. They have a range of approximately 45 m. Some modifications are made for indirect calculations by the Pythagorean theorem.
It is also worth noting that the devices are equipped with high capacity AAA batteries. The case of most versions is protected from moisture and dirt. Chips on average are designed to store more than 30 data. Devices have the option of calculating values. The device costs an average of 5 thousand rubles.
