The simulated doismeter operates using an STS radio frequency detection system which detects the presence of a simulated radiation field with the resultant reading displayed on the LCD Display .
The Safe-EPD features a 2 line 16 character LCD backlit display with single user button for selecting dose and rate functions. Instrument on/off is by a recessed button on the side of the dosimeter and there is a administrator menu accessible via a pinhole switch.
The menu allows users to set various parameters for the instrument including alarm threshold, dose and dose rate display, reading units (ySv or mR) and chirp rates.
The Safe-EPD uses the Safe-MiniSource as the field generator and will accumulate dose according to the proximity and shielding between the dosimeter and source. The rate of accumulation can be changed by using different Mini-Sources with different characteristics. Each source can be supplied programmed with a suitable isotope characteristic and activity level.
The Safe-EPD runs off 2 standard AAA cells giving an operation time of over 10hrs.
The Safe-Series of instruments offer the perfect solution for Ionising Radiation Training, Radiation Awareness Training and Homeland Security Training with simple intuitive controls, competitive pricing and low ongoing cost of ownership.
The STS Safe-EPD is not designed to be intrinsically safe and therefore should not be used in hazardous environments. The units are not waterproof and contain delicate and sensitive electronics which may be caused to fail if exposed to moisture. Units should be stored in a clean and dry environment, batteries should be removed if storing for more than 4 weeks.
Instrument response will be affected by environmental conditions such as the presence of large reflective surfaces, substantial metal structures and variable wall thicknesses.
