NJC61 Nonmetal Ultrasonic detector
Model No: NJC61
Purpose
² Testing building foundation piles by crosshole ultrasonic wave method.
² Inspecting concrete defects by ultrasonic method, such as uncompacted place, cellular hole area
² Detecting concrete strength by ultrasonic-rebound combined method
² Detecting concrete crack depth by ultrasonic method
² Detecting the wall defects of the hole by one transmitter and two receivers
² Detecting the strength performance of geotechnical investigation, rock, concrete, etc
