The 451P ionization chamber patrol meter is a hand-held battery-powered instrument designed for use in harsh and normal environments. The 451P patrol meter is characterized by a pressurized ionization chamber, which improves the sensitivity and energy response for measuring gamma and X-ray radiation.
The 451P type measuring instrument adopts micro-processor and LCD technology. It has a comfortable handle and a large diameter cushion gripper. It is designed to reduce fatigue caused by long time use. The outer shell of the measuring instrument is composed of light weight and high strength materials, and is sealed and moisture-proof. When ordering, users must specify dose units R or Sv. The display feature of the measuring instrument is to simulate bar charts. 21/2 bit indication reading, low voltage indication holding mode indicator. The user control part consists of an ON/OFF button and a status button. This instrument can adjust zero automatically and convert range automatically. When the surrounding light is dim, the circuit system of the display can automatically light the background light. Instrument application: Model 451P high voltage ionization chamber detector is widely used in medical care.
Model 451P high voltage ionization chamber detector is used to detect and diagnose radiation leakage and scattering around X-ray and radiotherapy rooms. It is also an ideal instrument for regional monitoring. It can be used for X-ray manufacturers, government agencies, national inspectors, research laboratories, biomedical and airport baggage inspection departments.
