Today, I received an inquiry from an Indian customer. This customer has previously consulted hand switches in our company and also consulted x ray collimator, image intensifiers and other equipment. Today I will introduce x ray collimator. We have three types of x ray collimators, NK103 can be used in portable X-ray machines, pet X-ray machines, mainly matching 125kv X-ray tubes. NK102 and NK103 are used for fixed X-ray machines, of which NK102 is mainly used for 125kv X-ray tubes, and NK202 is mainly used for 150kv X-ray tubes.
