New Product LCD Display Digital Height Gauge Measuring Tool

Altimeters have developed to the present stage and have multiple functions compared to the past. They are generally equipped with air flotation devices, temperature compensation, rechargeable battery packs, etc. inside their instruments. The purpose is to facilitate movement, quickly adapt to the measurement environment, and quickly, easily, and accurately obtain measurement data. Altimeters are unique in that they have a 2D detection function and can perform 2D measurements.

Laser ranging altimeters generally use two methods to measure distance: pulse method and phase method. The process of pulse method ranging is as follows: The laser emitted by the ranging instrument is reflected by the measured object and then received by the ranging instrument, which simultaneously records the time of the laser's round-trip. Half the product of the speed of light and the round-trip time is the distance between the distance meter and the object being measured. The accuracy of the pulse method for measuring distance is generally around+/- 1 meter. In addition, the measurement blind area of such distance measuring instruments is generally about 5 meters.
