Fluke 451P pressurized ionization chamber inspection instrument, ionizing radiation measuring instrument

451PThe pressurized ionization chamber monitoring instrument is from the United StatesFLUKEThe company has launched a handheld, highly sensitive ionizing radiation detection instrument, which combines the latest research results and manufacturing processes, and adopts multiple industry-leading new technologies to effectively ensure451PUnder normal conditions, it has the best detection performance among similar products, and good protection equipment can ensure even in extremely harsh environments451PStill able to work normally.

451PThe core detector of the pressurized ionization chamber patrol instrument is a large volume pressurized ionization chamber, which is used to measure gamma rays andXThe radiation of X-rays increases sensitivity and improves energy response. at the same time451PThe pressurized ionization chamber inspection instrument adopts the latest microprocessor and liquid crystal display technology internally. For convenient handheld operation, it is equipped with a comfortable handle externally to reduce fatigue caused by long-term use,451PA soft cushion grip sleeve with comfortable grip was also designed on the handle. Additionally,451PThe shell is made of lightweight and high-strength materials, with good sealing and moisture resistance.

451PIt adopts monochrome backlight, large font digital display LCD screen, and integrates analog bar chart.2^1/2The display has a low voltage indication and a hold mode indication function. When the surrounding light is dim, the circuit system of the display can automatically light up the background light. The user control section is composed of aON/OFFComposed of a button and a status button. During the measurement process, the instrument will automatically zero and automatically switch ranges.

In terms of data processing,451PThe body is integratedRS-232Interface, can be directly connected to a computer toWindowsUsed under the windowExcelSpreadsheets have enhanced the functionality of the instrument. The software of this instrument enables users to perform data retrieval, parameter selection, and provides a virtual instrument display with audio-visual alarm indicators. Users can improve the software to meet the needs of special applications.

Application:

451PThe pressurized ionization chamber monitoring instrument is used for measuringXDesigned for radiation leakage and scattering around optical diagnostic equipment and radiation therapy equipment, it can be widely used in the fields of medicine and health physics. Meanwhile,451PThe pressurized ionization chamber monitoring instrument is also an ideal instrument for on-site ionizing radiation measurement. Therefore,XRadiation manufacturers, government agencies, national inspectors, research laboratory personnel, and biomedical technicians often use it for baggage inspection and equipment maintenance at airports.
