For determination of Alpha, beta, gamma and x rays. LCD digital display reading, choose counts per minute (CPM), mR/hr (μ-SV/hr) and the cumulative count, up to a maximum of 350000 CPM or 110.0mR/h. each count is accompanied by flashing red LED and beep tips. When users set their own level of radiation is, the instrument will automatically send out sound and light alarm. This product conforms to the European CE certification requirements.

Radalert100 α, β, γ and χ multifunctional radiation to penetrate the radiation detector Geiger tubes and when cause ionization, Geiger counter tubes produce a pulsed current. Each pulse is an electronic detection and carry out calculations. Probe calculation in your choice of mode: CPM, mR/hr, or totals. S1 unit, using the CPS and μ SV/HR. count number of detectors detected every minute because of the radioactivity of any state changes. Average over a period of time that is more accurate, and the more accurate this time data.
