ALARMING POCKET DIGITAL DOSIMETER

Model # PDA-200([fig] ([fig] the READABLE one, PDA-200) FEATURES:

* 4-1/2 DIGITS TO 200.00 mR

* 700 HOUR BATTERY LIFE

* AUDIBLE AND VISUAL READOUT

* LCD CONTINUOUS DISPLAY

* TRULY POCKET SIZE

* BUILT IN MEMORY 

DESCRIPTION: PDA-200 accurately records total exposure and
by emitting a "beep" and
"flash" at each .01 mR of exposure gives and audible/visual
indication of rate as well as an accurate record of dose.
This dose is displayed continuously. 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 (6 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 with "dead" battery.
