This professional Radioactivity meter is a precise instrument to measure alpha, beta and gamma radioactivity. The Radioactivity meter has a wide measuring range and can be used for diverse measurements types as for sporadic measurements in situations, long-lasting measurements or for controls. The Radioactivity meter provides with a certified measurement of the environmental radiation as well as the radiation which is artificially increased up to 500 times over the limit value. This Radioactivity meter has diverse applications. This Geiger meter has been usually used in nuclear power stations. Everyday it is most commonly used in the control of imported goods, as well as to measure the food which has been previously irradiated. This Radioactivity meter can be also used to measure natural radioactive radiation as the one which appears near the sea and it fulfills all the requirements when controlling building materials. Radiation values can be recorded in the Radioactivity meter memory or they can be transferred to a computer to be valued by means of a device included in the delivery (software and RS 232 data cable).
