Description
Product Introduction
The ELγ-2000 intelligent gamma radiation meter is a detection instrument used to measure the radioactivity levels of natural stone, construction materials, industrial waste residues, and similar substances. In the construction sector, it is an essential tool throughout the stages of exploration, processing, production, and sales; it can also be employed for radioactivity monitoring in residential environments, renovation supervision, measurements at radioactive sites, and geological prospecting.
This instrument is a portable device featuring a 7-inch color touchscreen and a user-friendly interface. It is equipped with a high-capacity lithium‑ion battery to ensure extended measurement operation. With advantages such as high sensitivity, a wide energy response range, low power consumption, excellent stability, and ease of use, it can display the A, B, and C classification and application scope of the measured stone, as well as the count rate and absorbed dose rate of the measurement results. Furthermore, this instrument incorporates a suite of testing methods that outperform those of comparable devices, making its operation more accurate, straightforward, and efficient.
