Focus on Core Technologies

While specializing in a wide range of automotive sensors, we also offer an extensive portfolio of automotive parts. Our technological focus enables us to deeply understand the intricate workings of vehicles, resulting in products renowned for their precision, durability, and reliability.

Quality Is Our Commitment

Every step, from raw material sourcing to manufacturing, adheres to internationally recognized strict quality standards. We not only deliver high-quality products but also provide comprehensive quality assurance and a worry-free after-sales service system.

Our Philosophy

  • Precision Engineering: We believe that exceptional performance begins with precision down to the smallest detail. Every sensor we build reflects our relentless pursuit of accurate, reliable data.
  • Partnership Focus: We are more than a supplier — we are your problem-solving partner. We deeply understand customer needs and provide comprehensive support from product selection to after-sales service.
  • Sustainable Drive: We embrace our environmental responsibility. By developing products that reduce emissions and enhance fuel efficiency, we actively contribute to a cleaner, more sustainable global automotive industry.

Our Technology

  • For a Cleaner Planet: Our NOx sensors and other key products act as the “gatekeepers” of vehicle exhaust after-treatment systems. Through real-time, highly accurate monitoring, they ensure the SCR system operates efficiently, significantly reducing nitrogen oxide emissions and directly contributing to the protection of our shared blue sky.
  • For Your Peace of Mind: Safety is non-negotiable. Our sensors function like the vehicle’s “nerve endings,” continuously monitoring critical data and providing reliable input to the engine management system. They help prevent potential failures and ensure every journey is smooth and safe.
  • For Optimal Performance: We are committed to unlocking a vehicle’s full performance potential. By delivering precise data feedback, our products help engines maintain their ideal operating condition, achieving lower fuel consumption and stronger power output.

Our Strengths

  • A Vertically Integrated Global Power: We control the entire value chain — from core chip-level R&D to large-scale manufacturing. This ensures unmatched quality consistency, cost advantages, and supply stability.
  • A Forward-Thinking R&D Network: With research centers in the UK, Europe, and Asia, and collaborations with world-class engineering teams, we remain at the forefront of technological innovation.
  • Agile, Customer-Centric Service: Our marketing and service centers across key global markets enable fast, localized support, professional technical consultation, and flexible logistics solutions.
  • An Unwavering Commitment to Quality: We adhere to ISO international quality management systems, and our products have passed multiple global certifications. Our comprehensive warranty policy reflects our firm commitment to earning and honoring your trust.

  • Doliter's products are well priced and work perfectly. It took me about half an hour to set it up, and it took care of my check engine light and my sensor code.
