CH469 voltage output type optical detector module consists of  small-volume head-on PMT, high voltage power supply, voltage dividing circuit and amplifier circuit. The current signal generated by the PMT is converted into voltage signal after being converted and amplified. 

This product is characterized by miniaturization, low noise, wide response frequency bandwidth, strong anti-interference and adjustable gain. The gain can be adjusted by either voltage or potentiometer.

The product can be used in in-vitro diagnosis, fluorescence detection, material analysis and other fields.
