M2012光子計數(shù)器

The M2012 photon counting detector

M2012光子計數(shù)探測器是由端窗光電倍增管、高壓電源模塊以及比較成型電路組成的高靈敏度光子技術(shù)探測器。產(chǎn)品出廠前，各參數(shù)點已預設(shè)為值，用戶只需接通電源，將輸出端與計數(shù)單元連接即可使用。

The M2012 photon counting detector is a high sensitivity photon technology detector which is composed of end window photomultiplier, high voltage power supply module and comparative forming circuit. Before the product leaves the factory, each parameter point has been preset as the optimal value, the user only needs to switch on the power supply, the output terminal and the counter can be used.
