* THREE SINGLE CHANNEL ANALYZER WINDOWS,
  SWITCH SELECTABLE

* FULL AUTOSCALER FUNCTION AUTO-CYCLE

* FULL ANALOG FUNCTION

* CRYSTAL CONTROLLED

* ANY T/A GM, PROPORTIONAL, OR SCINTILLATION,
  ALPHA, ETA, GAMMA, X-RAY, NEUTRON PROBE

* LIGHTED SCALES

* SPLASH PROOF
  

DESCRIPTION: The PRS-5 is a sturdy portable instrument designed
for rugged field use, but incorporating both scaler and
ratemeter functions, single channel analyzer with three
presettable windows, variable high voltage 0-2500V. All
calibration pots are available from outside the case as
is the leakproof battery compartment. All closures are gasketed
or otherwise sealed to result in a splashproof instrument.
The meter is a taut band type for maximum ruggedness; additionally
both meter and LCD scaler readout are recessed for protection
against damage. Both displays are illuminated when the "illuminate"
button is depressed and remain lighted for approximately
6 seconds.

Pulses are seen via a red LED for visual service in dark
areas and the time base for scaler operation is indicated
by a flashing green LED. Accommodates pulses from all types
of detectors including scintillators, proportional and GM
detectors. Four ranges are incorporated into the ratemeter.
Gate times for the scaler may be set from 1 to 99 seconds
(and 1 to 99 minutes) and free running mode. The scaler
has an autocycle capability particularly useful for increasing
the accuracy of rate measurements and for operating optional
printer. Power switch and HV pot and other controls are
designed to prevent inadvertent change. The output of the
"beeper" is varied by a volume control from completely
silent to loud enough to be used in quite noisy environments.
Standard features include jack for optional AC adapter and
output jack for optional chart recorder. Yet the overall
instrument, including all of these functions and including
battery life up to 300 hours, still weighs only 62 ounces,
making it one of the lightest instruments of this type available.
