DTS positioning "different". Different from the peer product diversification strategy, DTS focuses on the research and development of commercial vehicle detectors, which is the only manufacturer in China that has focused on developing commercial vehicle detectors for 17 years. We are also the only testing instrument manufacturer that provides supporting equipment for full vehicle manufacturers.. With the support of strong technology and development capabilities, DTS has broken the traditional model of mainly selling products and passively providing after-sales service in the industry, and launched a new model of "SERVICE+PRODUCT". That is, flagship demonstration stores have been set up in cities above the national prefecture-level cities, share the core technical achievements of DTS, and provide proactive after-sales maintenance technical services and technical training for DTS product users.
