Feature: 1. Aspherical Lenses: The distance meter uses a new generation of aspherical lenses, which ensures the accuracy and greatly improves the stability. The linearity is good and it is very accurate. 2. Phase Method Modulation: The distance meter is modulated by the phase method and emits high frequency optical signals. The phase type laser ranging is usually suitable for the measurement of short and medium distances, and the measurement accuracy can up to the millimeter level. 3. Stable Reception: The aspherical optical lens of the laser distance meter has excellent low distortion and anti interference performance, which greatly reduces the influence of ambient light. 4. Quick Computing: The built in ST quick calculation chip of the distance meter completes the measurement almost in a flash from pressing the measurement to obtaining the data, and the response speed is only 0.1 seconds. 5. Integrated Design: The laser distance meter is made of integrated inner and outer rubber, high accuracy molds are cast at one time, and high strength ABS engineering plastics better ensure the body's safety.
