New Type - Lightweight 'COARA NX'
Achieved miniaturization and weight reduction (42kg → 13kg, approximately 1/3)! Installation on piping has become significantly easier!
"The only measuring device that can measure the total amount of concrete being poured." The continuous RI concrete moisture meter (COARA NX) can continuously and in real-time measure the unit water content of fresh concrete flowing through the pumping pipes. By installing it on the pipes of concrete pump trucks, the quality of the poured concrete can be monitored and managed. [Features] ■ Easy Installation The COARA NX has been made smaller and lighter compared to conventional devices, making installation on pumping pipes significantly easier. (Weight of the measuring device: 42kg → 13kg, approximately 1/3) ■ Remote Monitoring Capability By using the optional "SRENET," remote monitoring of the unit water content during pouring is possible. In environments away from the site, not only can the unit water content be checked, but also the pouring time. → NETIS Registration [CB-240049-A] "Concrete Unit Water Content Remote Monitoring System" *For more details, please download the PDF or contact us.

Since our establishment, we have developed many measurement technologies that utilize various types of radiation emitted by radioisotopes, particularly gamma rays and neutron rays, in the construction field, specifically the RI method. The characteristics of the RI method are "non-destructive," "rapid," and "high precision." Currently, based on the development of unique measuring instruments that leverage these characteristics and the proposal of investigation methods, we focus on consulting that comprehensively addresses issues related to ground and soil construction by combining soil and geological surveys. Additionally, we also engage in the sale and rental of these RI instruments. Please feel free to contact us if you have any requests.
