Key points for purchasing rangefinder telescopes

1. Accuracy. Choosing a suitable accuracy laser rangefinder according to the accuracy requirements of the use occasion is the primary consideration when purchasing. High-precision rangefinders on the market for power system measurements (such as Paz 360B, Australian New Instrument 600H) can reach 0.3 meters, while recreational golf rangefinders usually have a display resolution of only 1 meter, and the actual measurement accuracy is ± About 3 meters. When purchasing, it is recommended to use certificate products from measurement certification units.
2. Measuring range. According to the provisions on measuring range in the "Medium and Short-range Photoelectric Ranging Specifications (GB/T 16818-2008)", there are many measuring range components. Common laser rangefinders on the market include 600 meters, 800 meters, and 1000 meters. meters, 1200 meters, 1500 meters, 1800 meters, 2000 meters, 5000 meters, etc. It should be noted that the nominal measuring range is measured under the climatic conditions specified by the national standard. Under conditions such as haze and rainy days, the measuring range There will be shortening, so it is recommended to leave a certain margin when purchasing.
3. Angle measurement. In applications involving pitch angle and height such as electric power and ballistics, a laser rangefinder with an angle measurement function can be used. Laser rangefinders generally use an electronic compass or an inclination sensor as the technical solution for angle collection. , calibration is required after long-term use or strong magnetic field interference. The angle measurement accuracy of high-precision products can reach 0.3°, and conventional products can reach ±1°. When purchasing, you can choose according to actual needs. It is worth noting that some products integrate the function of measuring height, and the measurement of height is actually It is the result of calculation based on angle and linear distance. Therefore, the high-precision angle measurement function can ensure the accuracy of height measurement.
