Ideal for managing coarse-grained materials in embankments! The measurement area is more than 10 times that of conventional types!
The "SRID" is an RI density moisture meter that adopts a measurement method with a 360-degree scan around a source rod at a speed of one rotation per minute, achieving over ten times the measurement area compared to conventional methods (based on our company's comparison). Additionally, 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 an automatic floating scanning type (floating height of 5 cm), it is not affected by surface unevenness. ■ It measures by rotating within a circumference of 80 cm, providing over ten times the measurement capacity compared to our ANDES. ■ The measurement time is a total of 2 minutes, with 1 minute for BG measurement and 1 minute for on-site RI measurement at each location. ■ Standard measurement is unnecessary as it automatically corrects for source attenuation. *For more details, please download the PDF or contact us.

Company information
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.
