Tested precision instrument: Each radiation meter is subjected to rigorous endurance testing supervised by a certified NRC licensed lab. Each unit receives its own serialized test certificate. All radiation types: Reliably measures alpha, beta, gamma and x-radiation. (Depends on which model) Built in 90DB alarm Low power consumption: The built-in battery lasts up to three years. PC Software Menu control: An easy-to-understand menu guides you through all device functions. Data storage: Radiation monitor continuously stores recorded pulses in internal memory. Evaluation by computer: Specially designed software included with RADITECT II allows data download and evaluation on your laptop or PC. Compact design: Raditect Geiger counter is shock resistant, compact, light, and easily fits in your hand or pocket. Event Dose Calculation - If an alarm event occurs, RADITECT will store the radiation dose that was received during the event (beginning and end of elevated levels). This will give you the ability to make an assessment of your future risk. User selectable integration times LCD with Qualitative Information - RADITECT's most powerful feature. It reports radiation levels as Normal, Elevated, Warning/Unnaturally High, Danger /Long Term, Danger/ Short Term, or Fatal/ Short Term using a LCD display. It also indicates weather the radiation is increasing or decreasing and the rate. This will provide guidance to both experienced and inexperienced users as to how to deal with the emergency. No other device provides this type of information. Output RS-232 Serial Port. Active X control for remote PC control and monitoring - Allows you to set up a network of monitoring stations. Extremely Large Range - RADITECT will detect radiation from 0 to 1000 Rad/hr. Many other detectors will stop working at 10 Rad/hr or less.
