M2012光子计数探测器是由端窗光电倍增管、高压电源模块以及比较成型电路组成的高灵敏度光子计数探测器。产品出厂前，各参数点已预设为最优值，用户只需接通电源，将输出端与计数单元连接即可使用。

The M2012 photon counting detector is a high sensitivity photon technology detector which is composed of head-on photomultiplier, high voltage power supply module and comparative forming circuit. All parameters are set to their optimun values before the products leaves the factory.The user simply needs to switch on the power,connect the output to the counting unit.
