451P type pressure ionization chamber inspection instrument

Instrument introduction

451P type pressurized ionization chamber is a kind of portable battery powered instrument, which is designed for use in harsh environment and normal environment. The characteristic of the 451P type is a pressurized ionization chamber, which improves the sensitivity and improves the energy response for the measurement of gamma rays and X - rays.

451P type measuring instrument using micro processor and liquid crystal display technology, holding comfortable handle, there is a large diameter soft grip, is to reduce the fatigue caused by long time use and design. The measuring instrument case is composed of light weight and high strength material. When ordering, the user must specify a dose of R or Sv.

The display characteristic of the measuring instrument is to simulate the bar chart. 2 1/2 bit indicating value reading, low voltage indication holding mode indicator. The user control section is composed of a ON/OFF button and a state button. This instrument automatic zero adjustment and automatic range conversion. When the ambient light is dim, the circuit system of the display can automatically lighten the background light.

The ES-232 interface can be directly connected to the computer, and the Excel electronic table is used under the Windows display window, and the function of the instrument is enhanced. The instrument's software enables users to perform data retrieval, parameter selection, and provides a visual alarm indication of the virtual instrument display. Users can improve the software to meet the needs of special applications.

Instrument application:

451P type high pressure ionization chamber detector is widely used in medical and health care. 451P type high pressure ionization chamber detector is used for detecting around X ray diagnosis and radiation leakage radiation and scattering of the therapeutic room, is the ideal instrument for regional monitoring, can be used for X ray manufacturers, government agencies, state inspectors, biomedical research laboratories, and the airport baggage inspection department.
