 - Best 5 laser ranging modules companies 2022

Laser rangefinders are typically used by professionals in their day-to-day work because they enable fast distance measurements and other spatial measurements.

Why should you use a laser rangefinder?

A laser rangefinder is the most functional and technologically advanced measurement tool compared to an optical or ultrasonic rangefinder. In addition to their extremely precise measurements (+/- 1-5 mm per km), they can only be used by one individual. At construction sites and in large open spaces, optical rangefinders require at least two people to take precise distance measurements. Thus, laser rangefinders simplify measurement processes and reduce staffing requirements.

In addition, laser rangefinders are less likely to cause errors in measurement due to incorrect tool positioning and operator mistakes. Moreover, most professional laser rangefinders are equipped with electronic alignment aids, automatic calibration features, and the ability to take measurements using the Pythagorean equation or the “painter” feature. A continuous measurement, a delay measurement, a surface sum or difference measurement, and a volume measurement can also be performed with these tools. Enhanced processors and clear displays of measurement results installed in laser rangefinders make them more useful and functional, as well as more comfortable to use on a daily basis.

How do you choose the right laser rangefinder?

A device’s design and technical parameters should fit the industry, type of measurements, and terrain and weather conditions in which it will be used. If you’re measuring construction sites or facilities, you need a specific rangefinder, and if you’re measuring long distances in agriculture, forestry, or power, you need a different one.

Operating range
Every laser rangefinder has an operating range, which is one of the most important parameters.

Measurement accuracy
As important as a laser rangefinder’s operating range is its measurement accuracy. The most advanced laser rangefinders, such as the EXTECH DT40M, measure with an extremely precise tolerance of 1–2 mm, whereas most short and medium rangefinders have a 5 mm tolerance.

Laser dot diameter
Laser dots have a different diameter depending on their distance from and the type of object they are measured on. For example, wet plaster will make a laser dot much less visible than old brick walls or concrete underlayment. Laser rangefinders typically have laser dots with a diameter between 6 and 60 mm. When performing measurements that require prolonged observation of the laser dot, we recommend wearing high contrast glasses.

Minimum unit displayed
It is directly related to the precision of a measurement device. The lower the minimum unit displayed, the higher the measurement precision. The most precise laser rangefinders display measurement results in a resolution of 0.1 millimeters.

IP degree of protection
It is crucial to choose a laser rangefinder with an IP rating that is waterproof and dust-resistant when using it in the field. For construction work, it is best to choose one that is waterproof and dust-resistant. This will lower the risk of damaging the device in transport and while taking measurements in highly duty or moist environments, as well as during precipitation. IP54 or higher is the rating of the highest quality professional laser rangefinders.
