CH345

CH345 photon counting detector is a new generation of small photon counter with large sensitive area, which is composed of head-on PMT, high voltage power supply module, comparison and shaping circuit. The detector is characterized by low noise, wide linear range, high stability, good consistency, strong anti-interference and small volume. It is mainly used in weak light, precision measurement and analysis field. It has been widely used in many fields such as biology, medicine and chemistry. This product can directly output standard TTL signal to facilitate data processing.

Before the product leaves the factory, each parameter has been preset as the optimum value, the user just needs to connect the power supply and connect the output terminal to the counter.
