ALARMING POCKET DIGITAL DOSIMETER

Model # PDA-200 + mR

Model # PDA-200 + Sv

FEATURES: 4 DIGITS TO 200.00 mR DOSE AND DOSE RATE 700 HOUR BATTERY LIFE AUDIBLE AND VISUAL READOUT LCD CONTINUOUS DISPLAY TRULY POCKET SIZE BUILT IN MEMORY

DESCRIPTION: PDA-200+ accurately records dose rate and total exposure and by emitting a ''beep'' and ``flash'' at each 0.01 mR of exposure and gives audible/visual indication of rate as well as an accurate record of dose. When the alarm set-point is reached, a long beep and flash occurs. The PDA-200+ is completely digital, thus eliminating the inaccuracy inherent in any analog system. Recessed and tool-accessible dose-reset prevents unauthorized or accidental erasure of exposure history. The PDA-200+ is lightweight (3.5 oz.) and truly pocket size. Battery is available from outside case.

LED battery check indicates when less than 8 hours of battery life remains. Memory of dose is retained for at least 20 hours even with ``dead'' battery.
