There are many types of laser rangefinders currently on the market, and
different types have different functions. Here, the network editor will
introduce the types of laser rangefinders and the items that need to be
considered when buying.
Types of laser rangefinders:
Laser rangefinders are divided into handheld laser rangefinders and telescope laser rangefinders.
1. Handheld laser rangefinder: The measuring distance is generally within 200 meters, and the accuracy is about 2mm. This is a laser rangefinder that is currently widely used. Functionally, in addition to measuring distance, it can also calculate the volume of the measured object.
2. Cloud service laser rangefinder: The measurement data on the laser rangefinder is transmitted to mobile terminals such as mobile phones, tablets, etc. in real time via Bluetooth; the data can be transmitted to the cloud server through wifi networking, and shared with remote construction partners in real time Measurement data.
3. Telescopic laser rangefinder: The measuring distance is generally about 600-3000 meters. The measuring distance of this kind of rangefinder is relatively long, but the accuracy is relatively low, and the accuracy is generally about 1 meter. The main application range is long-distance measurement in the field.
One-dimensional laser rangefinder
Used for distance measurement and positioning; laser rangefinder
Two-dimensional scanning laser rangefinder.
Used for contour measurement, positioning, area monitoring and other fields;
Three-dimensional laser rangefinder
Used in three-dimensional profile measurement, three-dimensional space positioning and other fields.
Points to consider when buying a rangefinder:
1. Measuring range.
2. Measurement accuracy.
3. Use occasions.
It is basically divided into the following situations:
1. It only needs to measure the distance within a few meters or ten meters, and the accuracy is not high.
Suggestion-you can choose "Ultrasonic Rangefinder". However, the ultrasonic rangefinder has been eliminated in China due to its low accuracy and large environmental impact.
Note——The measurement effect of ultrasonic rangefinder is greatly affected by the environment, and its stability and directivity are worse than that of laser rangefinder, but the price is relatively cheap! Suitable for indoor measurement.
b. The measuring distance is not long, and it is mostly used indoors, requiring high accuracy!
Suggestion-you can choose "Handheld Laser Rangefinder".
c. Long measuring distance, mostly used outdoors!
Suggestion-select "Telescope Laser Rangefinder". (I.e. laser ranging telescope)!
Features—both a telescope and a rangefinder! With multiple observation magnifications, users can easily aim at the target for distance measurement by simply using the cross-sighting system inside the eyepiece! It uses transparent infrared laser emission and reception that is harmless to the eyes. Accurately measure the target distance, small size, light weight, and easy to carry!
