M1111型β探測(cè)器
The M1111 β detector
M1111型β探測(cè)器能夠測(cè)量低能β射線,因其優(yōu)異的抗力,能夠廣泛用于環(huán)境檢測(cè)、精密測(cè)量、科研等領(lǐng)域。本公司研發(fā)的M1111型β探測(cè)器主要由端窗光電倍增管、高壓電源模塊、信號(hào)成形電路、閃爍體等組成。
本產(chǎn)品具有簡(jiǎn)單方便、可靠性高及探測(cè)效率高等優(yōu)點(diǎn)。在出廠前,已經(jīng)過(guò)各項(xiàng)性能測(cè)試,接通電源,將輸出端與計(jì)數(shù)單元連接即可使用。
M1111 β detector can measure low energy β ray, because of its excellent anti-interference ability, can be widely used in environmental detection, precision measurement, scientific research and other fields. The M1111 β detector is mainly composed of photomultiplier, high voltage power supply module, signal forming circuit and scintillator .
The product has the advantages of simplicity, high reliability and high detection efficiency. Before leaving the factory, it has been tested in all aspects, connected to the power supply, the output end can be used with the counting unit.
