Our company offers several models of high-voltage amplifiers. After fully communicating with you about the application and requirements, we can provide a service of sample evaluation to support your purchasing decision. The evaluation method is through remote video. We will remotely operate and display the samples to the customers via video, and the customers can also send samples to us, and we will conduct experiments and shoot the results for the customers. Or we will send the samples to the customer's location for on-site evaluation. Which method to adopt will be determined by the current model of the sample, its status, and the availability time, etc., and will be negotiated with the customer at that time. For customers who have evaluation needs, please contact us or fill in the following information, and we will contact you as soon as possible.
