Cross-hole acoustic wave transmission method
Test the pile foundation integrity
High performance master processing unit
Three years host warranty

ZBL-U5 series Multichannel Ultrasonic Pile Integrity Tester

is the perfect device for cross-hole acoustic wave transmission method. This instrument is specifically designed for testing the pile foundation integrity by using acousti.

The Multichannel Ultrasonic Pile Integrity Tester is designed for sound wave transmission to detect pile integrity; Structural Concrete Compressive Strength, Crack Depth and Defect Detection; Continuous wall integrity testing; geological prospecting, rock integrity, weathering evaluation test; Rock, concrete and other non-metallic materials, mechanical properties testing.

The quality Stems from the professional:
1. Professional R&D team
2. Production department
3. After layers of quality inspection
4. Users at ease choice


Complete six sections of the test 

A pile test only once, can be measured 60 meters per minute

Waterproof and dustproof

Depth recording wheel with non-contact waterproof design

Wireless connections

Host and record the depth wheel using a wireless connection, get rid of the cable winding, damaged troubles

High performance master processing unit

Using high- performance A8+DSP master processing unit, with 10.4 British industry bright wide temperature LCD screen

The transducer bobbin is designed with a collecting ring

Can be free to send and receive signal cable at any time, no longer break the cable

The first wave of advanced positioning algorithm

The first wave of accurate positioning, a substantial increase in the accuracy of sound parameters interpretation of the scene, real-time reduction of pile

Everything OK structure detection

Can be ultrasonic- rebound integrated method of strength testing, non- compacted area and cavity detection, crack depth detection and other structural testing

Beautiful appearance

The use of modern industrial design, double injection molding machine shell, the body anti-skid, anti-fall, strong and beautiful
