Measurement of concrete compressive strength, non-destructive testing equipment for concrete structures.
The concrete tester "CTS-02V4" is a non-destructive device for measuring the compressive strength of concrete, used for inspecting the integrity of concrete structures. It strikes the concrete with a hammer and measures the mechanical impedance from the impact force waveform to estimate the compressive strength of the concrete. The V4 has further improved the accuracy of strength estimation for aging concrete structures by changing the hammer weight from 190g to 380g. It also enables strength estimation for high-strength concrete (up to about 150N/mm²). 【Measurement Targets】 ○ Estimation of concrete compressive strength (normal concrete, high-strength concrete) ○ Detection of the degree of deterioration (plasticization) of the concrete surface ○ Detection of delamination and lifting near the concrete surface ○ Detection of aggregate delamination on the concrete surface For more details, please contact us or download the catalog.

basic information
【Main Features】 ○ Enables strength measurement of high-strength concrete → By setting the high-strength concrete measurement mode in advance, you can select the calculation formula. ○ Measurement data can be directly processed on a computer → Connect the main unit to a computer via USB. ○ Measurement results are output as CSV files → Data processing with spreadsheet software has become easier. ○ Measurement results are displayed on the screen in about 1 second → Approximately 500,000 measurement data points are recorded in the main unit along with waveform data. ○ Introduces the concept of measurement planes → Average values of multiple impact results can be obtained at all measurement points. ○ When the number of impacts at the same measurement point exceeds 20, it switches to the conventional point mode. ○ The measuring device operates on four AA batteries → Rechargeable secondary batteries can be used. → It can also operate on power from a computer's USB. → With alkaline batteries, continuous measurement for 12 hours is possible. ● For more details, please contact us or download the catalog.

Company information
Nitto Construction Co., Ltd. aims to be a comprehensive construction company that not only contributes to the development of local social infrastructure but also creates new technologies and brings innovation to construction techniques. Since 2000, Nitto Construction has established a non-destructive testing division to expand into new business areas, focusing on non-destructive diagnostic technology for concrete structures. In 2003, with subsidies from the Ministry of Economy, Trade and Industry and Hokkaido, we developed the Concrete Tester (CTS). The Concrete Tester is a device that allows for the non-destructive and simple diagnosis of concrete strength, deterioration, and delamination, and it is widely sold not only in Japan but also overseas in countries such as South Korea and the United States. In July 2009, we received the Minister of Economy, Trade and Industry Special Award at the "3rd Monozukuri Japan Awards," and in October 2010, we were awarded the Encouragement Award from the Small and Medium Enterprise Agency at the "Local Invention Awards." Moving forward, Nitto Construction aims to continue to refine and develop these technologies, striving to be a technology-oriented construction company that is needed by everyone.
