Precautions measurement: Try to keep the body and measuring the vertical wall, especially when the measured distance, the more vertical, the higher the accuracy of the measurement data, whereas the greater the slope, the greater the error. If you do not maintain a balance, it appears garbled, holding hands is best measured when comparing measurements to maintain balance. Product Description: Ultrasonic range finder in foreign countries is called "electronic tape measure" applicable to the construction, renovation, construction and other places, can do beyond the capacity of traditional tape measure. Restaurant sales of ultrasonic range finder based on data provided by the manufacturer is already relatively good performance on the current international products, and market share in Europe is very high, compared to other brands in the ultrasonic range finder launch angle, anti-jamming processing With the obvious differences in the other aspects. Original products, quality is guaranteed. · Instantaneous or continuous measurement · Area and volume calculations · Laser positioning Features: * The use of ultrasound to a vertical distance from a point to a plane of accurate measurement. Press the button, the instrument can emit ultrasonic encountered obstacles, you can back, and then the instrument, you can display the actual distance. Length can be used to measure housing, width, height, very convenient and practical! Engineers must have! Technical parameters: 1. Range: 0.5-18.0m 2. Accuracy: ± (1cm + 0.5% × distance) 3. Power: 9V battery 4. Resolution: 1cm 5. Power: 0.02W 6. Temperature compensation: 0 ~ 38 ℃
