Ultrasonic Ranging mainly used for indoor, outdoor If it is used, select no wind and atmospheric conditions better weather, ultrasonic range finder does not apply to windy environment, because the wind would sound wave propagation speed and direction causing interference. This product is made of high quality ultrasonic sensor refined specifically for ultrasonic ranging, detection range of 0.6--18 meters, and can calculate the area, volume and other parameters, measured values ??can be stored. This product is a high-tech products, the majority of products are exported to European markets. Features: * use of ultrasound for certain vertical distance from a point to a surface for accurate measurements. * You can select metric or imperial measurements, calculation, or convert between the two formats. * Internal automatic temperature compensation, measure the distance from the ambient temperature. * Available for guiding the laser measurement, in order to more accurately measure. * Auto-off function Technical parameters: 1. Range: 0.6-18.0m 2. Accuracy: ± (0.1m + 0.5% × distance) 3. Power: 9V battery 4. Resolution: 1cm 5. Power: 0.02W 6. Temperature compensation: 0 ~ 38 ℃
