Drop Weight Impact Deflectometer ASTM

Product Description

Product Description
Light Drop Weight Tester Product DescriptionEVD-W type Light weight deflectometer is used to determine the deflection capacity of the subgrade under the dynamic load, thereby evaluating the bearing capacity and deformation of the subgrade. It is suitable for monitoring and testing the construction quality of railway, highway, airport, urban traffic, port, wharf and industrial and civil buildings under dynamic loads, especially in narrow areas, such as bridge (culvert) transition section and shoulder detection, existing line subgrade, etc. Compared with the static load test, the instrument can simulate the impact effect of high-speed train on subgrade, which can better reflect the actual stress of subgrade soil. It can quickly measure the dynamic deformation modulus Evd value. PRODUCT FEATURES 1. The first APP data processing method in China has realized wireless data acquisition, wireless transmission and voice prompt function. 2. Provide a cloud transport port dockable engineering detection and management system to provide reliable data sources for real-time data acquisition, online data analysis, large data management, etc. 3. Imported sensors and some components are used, which has high test accuracy and more reliable test data. 4. The wireless Bluetooth micro printer can print directly on the spot to ensure the accuracy and objectivity of the test results. 5. It is easy to operate and fast to test. It takes only 35 seconds to detect a point. 6. The Evd value is calculated automatically and the curve is displayed accurately and intuitively. 7. Non-nuclear radiation and exhaust gas pollution, safe operation and environmental protection.Parameters Test coverageProduct ModelEVD-WApplication Soil TypesSoil-rock mixed fillers with particle size less than 1/4of the diameter of loading plateTest scope10Mpa≤Evd≤225MpaTest impact depth0~500mmWork environmentTemperature: -10~40℃ Humidity: ＜90%HR Work environment Loading deviceWeight: 15kg drop weight:10kgDropping height of drop hammer: 700±20mmMaximum impact force: 7.07kNShock duration; 18±1msLoading plateWeight:15kg Diameter: 300mmThickness: 20mm Handheld hostSpecificationsScreen size: 5 inchesSubsidence test rangeVolume: 145x70x10mmWeight: 110gStorage capacity0.10mm~2.00mmDepending on the memory of the phone, 10G storage capacityPower supply modeDepending on the cell phone batteryDisplay modeMobile App. English DisplayData transmission modeData wireless transmission, data cloud transmissionPrinterConnection modeWireless Bluetooth Printing Packing specification Host boxMaterial: Engineering plasticsVolume: 420x140x335mmWeight: 4.5kg Outer packing boxMaterial: Aluminum alloyVolume: 1220x395x380mmWeight: 56kgApplicationContact USCangzhou Lovely Technology Co., Ltd. is specialize in Nondestructive Test Instrument and Material Test Machine over 10 years, With advanced technologies and best customer service, Our product has exported to more than 100 countries and regions, which win favorable comments from customers worldwide.We adhere to the high standards of product quality, strict requirements, adopting the world-class production equipment, advanced management and production experience, developing the high-quality testing equipment.We have has strong sales team and a comprehensive service process to serve end customers around the world.If you have any inquiry or concern,Sales and after service department will reply you within 24 hours.Our Customers and patent certificatePacking & DeliveryWhy Choose us ?get our in-time reply via email or telephone or instant messenger;get best product with excellent quality and competitive price;One year guarantee for whole machine 24 hours technical support by email or calling teach you to install and operate,always enjoy our considerable & full-side after-sales service; feel very convenient since we can help you sourcing and ship products from different factories via one shipment, which to a large extent save your time and cost; easily make the payment via West Union, Paypal, T/T for small value order;
