The BNS92S is a nuclear radiation measuring device with two operational modes. It operates as a gamma radiation dose and dose rate meter while sits in the carrying case and functions as a contamination meter when it is taken out of it. The thresholds for dose and dose rate alarms are manually adjustable. When the radiation level exceeds one of the thresholds an audio alarm signal is activated. The LCD display of the instrument shows the actual measurement values and other functional information as well. The device has a digital bidirectional communicaton interface. Used either in routine environment checking or in accident area monitoring, BNS92S is a rugged and reliable device with practically proved outstanding features.
