PORTABLE VEHICLE TRANSIT MONITOR

Model # PVM-TA
Model # PVM-TB
Model # PVM-L/O

FEATURES: COMPLETELY PORTABLE OPERATES ON RECHARGEABLE BATTERIES or AC CAN ALARM AT 7 µ R/hr RISE WITHIN 1 SECOND (TA) SEES AND CAN ALARM AT 1 µ R/hr ABOVE BACKGROUND (TB) COMPLETELY WEATHER PROOF HIGH SENSITIVITY DETECTORS (PLASTIC SCINTILLATORS 792 in3 EACH) DYNAMIC BACKGROUND SUBTRACT FAST RATE OF CHANGE DESIGN CONTINUOUS OPERATION: ``SET AND FORGET''

DESCRIPTION: Portable control / alarm module plus two portable weather proof detectors each with Plastic Scintillators 792 in³/detector. Rate of change electronics with audio and visual alarms. Operates on built-in rechargeable batteries or 110/220 AC. Operation for rugged outdoor use as well as indoors. Model PVM-TA is a high sensitivity Gamma Monitoring system for determining possible radiation contamination in containers or vehicles on a non-pause basis. Since the operation of this instrument is based on rate of change in radiation, it will reliably pick up contamination as it passes near the monitor. Model PVM-TB achieves greater sensitivity by stop and count approach. This system can be set-up at the road side or in a parking lot. It can be mounted to a fence post or at a loading dock or at a roadway station. Background is continually updated and subtracted thus giving net vehicle reading.

PORTABLE VEHICLE TRANSIT MONITOR

Model # PVM-TA
Model # PVM-TB
Model # PVM-L/O

PORTABILITY:

• Battery Operation.
• Each element is housed in weather proof high impact plastic case with sturdy carrying handles.
• Detectors are shipped with built in deployment stand (Model DS-4).
• Detectors have Built in wheels plus industrial grade, easy to use, reusable straps.

PVM-L/O uses the same detectors as the other PVM models, but has simplified LAM-10L ``Alarming Ratemeter'' electronics, Instead of ``Rate of Charge'' electronics.

Available as a Fixed Unit (Model# VMF-TA) in a Metal Housing.
