Last summer, we received an inquiry from Thailand. The customer was a company engaged in waste oil recycling and re‑refining, needing to purchase a batch of analytical instruments for testing the quality of recycled lubricants, including a kinematic viscosity tester, an open cup flash point tester, and a moisture tester.
Interestingly, the customer attached a photo directly in the email — it was a closed cup flash point tester with our old‑style label on it, covered in oil stains, but the screen was still lit.
The customer wrote in the email:
"We bought this instrument from a local Thai trader in 2015. At the time, we didn't know you were the original manufacturer. Over eight years, it has been dropped twice by workshop workers and soaked in oil once, but its test results are still accurate. Now we are planning to expand our laboratory and want to source directly from the original factory. Do you still produce this model?"
This surprised and touched us at the same time.
Our technical team looked through old archives and confirmed that this was a model launched in 2012 and upgraded in 2018. Considering the customer's operating habits and existing workflow, we did not push the new model. Instead, we proactively proposed: using the old model's operation interface and external dimensions, but equipping it with our latest temperature control technology and circuit system — an "internal upgrade" that would give the customer an instrument retaining the original feel while having the core performance of the new version.
After sending the proposal, the customer's technical manager quickly called us. He said something that left a deep impression on me:
"You didn't push the new model just to make more money. You truly considered things from our usage perspective. A manufacturer like this deserves a long‑term partnership."
In the end, the customer placed a one‑time order for five instruments. Three months after delivery, they added an automatic distillation tester. What made us even happier was that this customer voluntarily posted a video of our instrument in his industry group chat, with the caption:
"After eight years of searching, I finally found the original factory. The quality is still the same, but the service is ten times better than I imagined."
Through his referral, we received inquiries one after another from three similar companies in Thailand, Vietnam, and Malaysia. When one of the new customers signed the contract, he said something very practical: "I've seen that eight‑year‑old instrument. A piece of equipment that can run for eight years without major trouble — I have nothing to worry about."
This experience gave us a deep insight: in the field of petroleum analysis instruments, the best advertisement is not a large screen at a trade show, but the instrument that has been running steadily for years in a customer's laboratory.
An eight‑year‑old instrument quietly spoke for us for eight years. All we can do in return is to repay every bit of trust that comes from afar with the same solid quality.
— Dalian Analytical Instruments Factory: forty years as always. Your laboratory also deserves an instrument that will be remembered many years from now.
