Best laser rangefinders for construction for 2020

The construction tape is a good device, but it is only popular in the household. Professional builders prefer modern solutions that are more accurate and more effective.

Measurement tools are used in construction, engineering, factories, landscape design, etc. Also, this device will become an irreplaceable assistant in home repairs. Most of the products are of good accuracy and low price. And in order to find the right option, the editorial staff of the site "bestx.htgetrid.com/en/" has prepared for you a rating of the best laser rangefinders for construction for 2020.

Features and purpose

The laser rangefinder is one of the best devices for measuring distances between two objects, while working with high accuracy.

This element has no special functions, it only determines the distance from one point to another. Despite this, using such a device is many times more comfortable than standard mechanical versions. All measurements can be carried out by one person, which significantly saves labor. To use such a tool, the builder does not need to have any specific knowledge, it is enough just to turn on the device and carry out the appropriate operation.

All measurements are carried out remotely, an employee or foreman does not need to walk from one point to another, it is enough to direct the working side to the surface and look at the equipment display, where all the information is displayed. The tool shows excellent results in the apartment, but it is more popular when working outdoors.

Such a device is able to simplify most of the measurement work. All operations are performed with maximum accuracy, which minimizes the physical labor of the employee. The device is useful when it is important to know the length of the span between the wells or to find out about the current length of pipes. But besides this, the rangefinder is also used to accomplish other tasks. This is a great device that suits every area where you need special precision, with minimal time investment.

In addition to measuring the length, the instrument is capable of performing other equally useful tasks, including:

• Determination of the area of ​​a room or room. If a person needs to accurately determine this value, then using a rangefinder, he will do it without any problems. To do this, it is enough to indicate all the main parameters - length, height, width. The tool will then automatically generate the correct result.
• Also, the rangefinder is indispensable for identifying the volume of a specific container or container.
• If necessary, the tool is used to obtain values ​​according to the Pythagorean theorem.

At the heart of this device is an LED emitter, which is projected onto a specific surface using a color point. The distance is determined along the length of the beam. Each reading is displayed on the instrument screen.For control, special buttons are used, which are located on the body of the laser rangefinder, with their help you can configure the modes for a specific situation.

In addition, those units of measurement are selected on the control panel that are suitable for measurement. The range of choice is wide, a person can take measurements in centimeters, meters, decimeters and even in millimeters. Some devices have additional elements that can facilitate work, such as a video camera. In terms of dimensions, the device looks more like a standard 5-6 inch smartphone, but there are models that exceed this parameter many times.

Principle of operation

The operation of this instrument is as simple as possible, the readings are taken according to the time during which the sent beam will be reflected from the surface and return back, this is also called the response time. But, despite such lightness, the design determines all values ​​with an accuracy of tenths. All obtained calculations are converted by the microcontroller and displayed on the LCD in human-readable units.

But this way of working is not typical for all devices, some, especially professional products, work according to a different principle:

• Rangefinders not only emit a laser beam, they also produce a series of small pulses that have a sinusoidal appearance.
• The frequency of such signals does not change with length and is always the same.
• As soon as the beam is reflected from the surface, the sinusoid changes.
• The last stage is reading the obtained values ​​using a microcontroller;
• The information received is shown on the display.

This simple operating principle allows everyone to carry out measuring operations without additional questions. It is enough to read the instructions in order to understand how to act in one case or another and how to turn on the device, as well as set the values. There is nothing difficult in this, even an inexperienced builder can handle such work.

What to look for when choosing

The first thing to know when buying a device is the scope and frequency of use. If you plan to use the device at a distance of up to 30 meters, then any Chinese product is suitable for such operations. Their cost ranges from 1,500 to 6,000 rubles. It is important to understand that the cheaper the product, the worse its durability, but this only applies to non-brand devices. If a person buys a branded instrument for little money, then it will last several times longer, since a high-quality element base is used there. If you need to measure long distances (from 300 m), then it is best to buy professional devices costing from 20,000 rubles. Such a device is more suitable for taking measurements outdoors.

But besides the price and range, there are other, equally important technical characteristics that should not be forgotten when buying a device:

• For high-quality measurements on the street, it is important to find out about the presence of a built-in sight, which can be either optical or digital. So the employee will eliminate any errors and do the job efficiently. If you ignore this parameter, then there is a high probability that the device will make a mistake in the calculations and the person will receive an inaccurate result. However, this is typical only for an outdoor tool, if you plan to use the rangefinder indoors, for example, when working with stretch ceilings, then any good device will do.
• In addition, the minimum length that the tool can measure is taken into account. Most buyers ignore this parameter, so they face problems when they are faced with the task of measuring the distance up to 50 cm.Of course, an experienced user can use a ruler or a regular tape measure, but if these tools are not at hand, the work will become more difficult.
• Minimum error. Everything is simple here, it is important to understand that this parameter depends on the cost of the device and the higher it is, the lower the error. Finding a cheap product with minimal deviation is almost impossible. It is important to understand that all Chinese devices have an inaccuracy of 1.5-3 mm.For expensive options, this indicator is several times less and is up to 0.5 mm, in some cases up to 1 mm.
• Special abilities. It is important to understand that the more options the manufacturer provides, the higher the cost of the product. The most common devices that are used in home repairs and are able to measure up to 20 meters will cost the user 2-4 thousand rubles. Buying expensive instruments for outdoor measurement, the cost increases 3-5 times.

What to choose, each person determines independently. If the user often works with such a tool, then you should not look at cheap models. In the opposite case, you can save several thousand and find a suitable product that will last a long time, and the error will be minimal. Also, we must not forget about the brand, it is better to overpay and get a quality product with a guarantee than a cheaper one of an unknown brand, but without it.

How to use the device indoors?

It is important to follow the general rules in order to make measurements with minimal deviation. Some of them are indicated in the instruction manual, while others come with experience. There is nothing difficult when taking measurements, everyone is able to cope with this event, even the one who holds this device for the first time. The general picture on the correct use of a laser rangefinder looks like this:

• First you need to turn on the device. All rangefinders are powered by an independent power source. These can be either standard finger-type batteries or full-fledged batteries. To turn it on, hold down the corresponding key.
• As soon as the backlight appeared on the screen, it means that the device turned on. Next, a specific mode is selected, which depends on the type of room and the characteristics of the measurements. If the standard model is used, then you should specify the unit of measurement and that's it.
• Place the instrument on the first object to measure from. To install the product correctly, just look at the special marks on the case, which will help you perform this action.
• After placing the device in the chosen place, it is worth holding down the button to take measurements. The rest of the actions do not require any special user intervention, as they are performed automatically.
• After a couple of seconds, the employee is displayed all the information received.

It is important to remember the temperature of the room, as well as sufficient lighting. It is desirable that it be positive, as this can affect the final result. Light should be enough too. For outdoor devices, this is not such a categorical parameter, since it is capable of working under any conditions and in any lighting.
