STS are pleased to announce that the Thermo RadEye(tm) G-10 and GF-10 Safe-Series simulators are now available as part of the Safe-Series simulation range. These all new simulators use a real unmodified Thermo RadEye with the GM tube removed and the STS simulation circuit added. The STS circuit generates pulses from the radio signal received from the simulated source and send these pulses directly to the RadEye circuit outputing as a standard reading in Sv`s.
