Product Description

 

Instrument introduction
The Concrete Ultrasonic Detector is an intelligent instrument for non-destructive testing ofnon-metallic materials and components such as concrete, rock, ceramics, graphite.plastics, etcusing ultrasonic pulse detection technology.it combines ultrasonictransmission, dual-channel synchronous reception, high-speed digital signal acquisitionautomatic measurement of acoustic parameters, digital analysis processing, real-timedisplay of results, digital storage and output it can be used for concrete pile integritytesting, strength testing, structural internal defect detection and crack detection.The GTJ-U900 Concrete Uitrasonic Detector inciudes the following functional modules.
(1) Sound wave transmission method to detect the integrily of the pile (referred to as"measuring pile");
(2)Ultrasonic method is not dense and cavity detectlon (referred to as "measurement");
(3)Ultrasonicrebound comprehensive method for testing concrete strength (referred to as"measured strength");
(4)Uitrasonic fat test method for detecting concretecrack depth (referred to as"'sampling");

Main performance indicators

Precautions
(1)Avoid water ingress,
(2)Avoid high temperature (>50°C);
(3)Avoid close to strong magnetic felds, such as large electromagnets, largetransformers, etc.,
(4)to avoid the violent impact ofthe transducer
(5)The necessary protective measures should be taken when using in humid, dusty orcorrosive gas environment,
(6)The instrument should be stored in a ventilated, cool, dry place,
(7) When the instrument is not used for a long time, the rechargeable battery will naturallydischarge, resulting in a decrease in power. it is recommended to recharge before use,
(8)Do not open the instrument case without permission.
(9) Please connect the signal line and the transducer in the offstate, and pay attention toconfirm the order of the plane transducer receiving and transmitting lines to avoid thewrong insertion.
