"ANDES" is a non-destructive measuring instrument that utilizes sealed radioisotopes (radioactive isotopes: RI). It can be easily transported to the necessary location at the necessary time, allowing for data to be measured simply, accurately, reliably, quickly, and safely. It can be used for "soil compaction management" in various earthworks, including roads, airports, dams, land development, embankments, and backfilling of pipelines. 【Features】 - On-site determination of the compaction state (degree of compaction) of embankments - Capable of assessment for any soil type - Measurement time is one minute per location, allowing for multiple measurements in a short time - Printing and statistical calculation functions for measurement data - Capability to store measurement data in the measuring instrument itself - Minimal human error factors in measurements - Easy data organization using a dedicated application on smartphones or PCs *The specifications of the measuring instrument include general specifications (Ministry of Land, Infrastructure, Transport and Tourism, prefectures including cities and towns, and private construction) and NEXCO specifications.

The automatic scanning RI density moisture meter "SRID" adopts a 360-degree scanning measurement method (1 rotation/min) around a source rod, achieving more than 10 times the measurement area compared to conventional methods (based on our company’s comparison). Furthermore, it features an automatic correction function for uneven surfaces using a non-contact distance sensor, eliminating the need for ground leveling work. 【Features】 ■ As it is a floating automatic scanning type (floating height of 5cm), it is unaffected by surface unevenness. ■ It measures by rotating within a circumference of 80cm, achieving more than 10 times the measurement area compared to our ANDES. ■ The measurement time is a total of 2 minutes, with 1 minute for BG measurement at one location and 1 minute for on-site RI measurement. ■ Standard measurement is unnecessary as it automatically corrects for source attenuation. *For more details, please download the PDF or contact us.

The WARP-mini, a simplified RI moisture meter (successor to WARP), is a measuring instrument developed with the concept of being lightweight, compact, and quick to measure as a new simple moisture content meter. In the quality control of embankments in ICT civil engineering, managing the moisture content of the target materials is crucial, and by using the WARP-mini, which measures in just 45 seconds, it is possible to quickly check the moisture content of the target materials. 【Features】 ■ Measures moisture content in just 45 seconds ■ No drilling or prior preparation needed; simple operation by just placing it and pressing a button ■ Ideal for measuring construction moisture content in ICT civil engineering ■ Measurement data can be stored in the internal memory of the main unit, and data organization is possible on a PC or smartphone *For more details, please download the PDF or contact us.

When used in conjunction with RI instruments (such as our products ANDES and SRID), the simple drilling machine assists in the driving work, greatly contributing to labor reduction and time savings. Additionally, it can handle hard ground, making drilling easy for anyone.

The "2-Hole RI Density Meter" is a frame-type two-hole measurement method in which two conduit frames are embedded in the fill layer at a 45-degree angle in parallel. One conduit frame contains a gamma ray source, while the other contains a gamma ray detector. The measurement is conducted by simultaneously raising both the source and the detector from the bottom of the embedded conduit frame, continuously measuring the compaction density in the depth direction between the frames. Therefore, it is suitable for quantifying the relationship between the compaction energy within the fill layer and the rolling effect, which is essential for fill construction (thick-layer construction). 【Features】 ■ Achieves continuous measurement in the depth direction with a two-hole system ■ Accurately quantifies the relationship between compaction energy and rolling effect within the fill layer ■ Enables accurate data measurement through gamma ray transmission method ■ Capable of measuring materials mixed with gravel *For more details, please download the PDF or feel free to contact us.

"SPITER" is a new one-hole RI density and moisture meter that can measure depths that conventional surface-type RI density and moisture meters could not measure. It can measure density and moisture not only at the ground surface but also in areas deeper than 50 cm. By using an extension rod, measurements can be taken at any desired depth, allowing for an understanding of the depth distribution of density and moisture within the ground. Additionally, by utilizing the installed guide pipe, it is possible to track the temporal changes in the density and moisture of the ground. 【Features】 ■ Achieves density and moisture measurement at depths that conventional surface-type RI density and moisture meters could not measure. ■ Applicable for compaction management of thick layers exceeding 60 cm in layer thickness. ■ Enables tracking of temporal changes in the density and moisture of the ground using the installed guide pipe. *For more details, please download the PDF or feel free to contact us.
