The ZBL-U5100 operates on the principle of ultrasonic testing, where sound waves are sent through the material. By analysing the time, it takes for the waves to travel through the object and return, the instrument can calculate characteristics like the pulse velocity, which is then correlated to the material's strength and integrity.  

Chromosomic is an instrument for ultrasonic pulse velocity through transparency which can be used to investigate poles, truss, diaphragms, laboratory samples and many other structures made of concrete or stone.
It performs measurements with direct, indirect and semi direct methods. 

It is a portable, non-destructive testing instrument used to accurately detect and measure the position, distribution, and diameter of steel bars (rebars) within reinforced concrete structures. It also measures the thickness of the concrete protective layer over the rebars.

It can be connected with our company's ZBL-S2 series digital rebound tester to directly import the rebound data for ultrasonic-rebound comprehensive method data processing. Eight-inch screen, capacitive touch screen, friendly software interface, simple and easy to use.

The ZBL-U5200 is a multi-channel ultrasonic detector for civil engineering, featuring a 5.7-inch TFT display, touch screen and keys for operation, and internal electronic hard disk and U-disk for data storage.
