What are the most common kinds of laser distance meters?
1. Handheld laser rangefinder
The measurement distance is generally within 200 meters, with an accuracy of about 2mm. This is currently a widely used laser rangefinder. In terms of functionality, in addition to being able to measure distance, it can generally calculate and measure the volume of an object.
2. Cloud service laser rangefinder
Real time transmission of measurement data from laser rangefinder to mobile terminals such as mobile phones and tablets via Bluetooth; Through WiFi networking, data can be transmitted to cloud servers for real-time sharing of measurement data among remote construction partners.
3. Telescopic laser rangefinder
The measurement distance is relatively long, generally ranging from 3.5 meters to 2000 meters, and there are also ranging telescopes with a maximum range of about 10 kilometers. Due to the collimation requirements of ranging telescopes, a blind spot is formed below 3.5 meters, while laser telescopes above 2000 meters generally use YAG laser with a wavelength of 1.064 microns. In order to achieve a larger measurement range, the laser power is relatively high. It is recommended that users pay attention to laser protection. The main application scope is outdoor medium and long-distance measurement.
In addition, it can also be divided into one-dimensional laser rangefinders: used for distance measurement and positioning; 2D laser rangefinder: used in contour measurement, positioning, area monitoring and other fields; 3D laser rangefinder: used in fields such as 3D contour measurement and 3D spatial positioning.
PD-S laser rangefinder product features: maximum distance: 60 meters, accuracy: ± 1.5mm, continuous measurement, the smallest and most compact rangefinder to date.
