Laser rangefinder is a professional tool, which includes many types of laser rangefinder, and handheld laser rangefinder is one of the most common laser rangefinder, the following to learn more.
Meaning of handheld laser rangefinder.

Handheld laser rangefinder is an instrument that uses a laser to accurately determine the distance to the target. Laser rangefinder in the work of a very thin laser beam to the target, by the photoelectric element to receive the laser beam reflected from the target, the timer to determine the time from the emission to the receipt of the laser beam, calculate the distance from the observer to the target. It is capable of measuring distance, area and volume, both indoors and outdoors.

The main categories of handheld laser rangefinder.

1. One-dimensional laser rangefinder is used for distance measurement and positioning.

2. Two-dimensional laser rangefinder (Scanning Laser Rangefinder) is used for contour measurement, positioning, area monitoring and other fields.

3. 3D Laser Rangefinder is used for 3D contour measurement, 3D spatial positioning and other fields.

Laser rangefinder light weight, small size, easy to operate fast and accurate, its error is only one-fifth to several hundredths of other optical rangefinder, and therefore is widely used in terrain measurement, battlefield measurement, tanks, aircraft, ships and artillery range to the target, measuring the height of clouds, aircraft, missiles and artificial satellites, etc.. It is an important technical equipment to improve the accuracy of tanks, aircraft, ships and artillery. As the price of laser rangefinder keeps coming down, the industry also gradually starts to use laser rangefinder. A number of new micro rangefinders with the advantages of fast range, small size and reliable performance have appeared at home and abroad, which can be widely used in industrial measurement and control, mining, ports and other fields.

Handheld laser rangefinder purchase instructions.
1. Only need to measure the distance within a few meters or a dozen meters, and the accuracy requirements are not high. It is recommended that ultrasonic rangefinder can be used. However, due to the lack of precision and environmental impact, the ultrasonic rangefinder has been eliminated in the country. The effect of ultrasonic rangefinder measurement is affected by the environment, and the stability and directionality is worse than laser rangefinder, but the price is relatively cheap! Suitable with indoor measurement.
2. The measurement distance is not long, mostly used indoors, high accuracy requirements! It is recommended that handheld laser rangefinder can be purchased.
3. The measurement distance is long, mostly used for outdoor use. It is recommended that you can purchase telescopic laser rangefinder.
Handheld laser rangefinder precautions.
Handheld laser rangefinder because of the use of laser for distance measurement, and the pulse laser beam is a very concentrated energy monochromatic light source, so do not use the eye to align the launch port directly, and do not use the aiming telescope to observe the smooth reflective surface, so as not to hurt the human eye. Be sure to measure according to the safety operation specifications in the instrument manual. When measuring in the field, do not point the instrument launch port directly at the sun to avoid burning the instrument photosensitive components.
