Verified contact details
Telephone: +86 571-89712238. Email: [email protected], [email protected]. Please include the category you are asking about, a plain description of the inspection or imaging task, the equipment already in use if any, and the items you need confirmed in writing. A task description produces a more useful reply than a category name alone, because it lets the supplier confirm fit for your task rather than repeat a general description.
What to ask for in writing
Ask for written confirmation of the proposed option and its fit for your described task, the quoted price and what it includes, availability, lead times, and any documentation you need. No price, minimum order quantity or lead time is stated on this site, because none has been verified for publication. Before payment, confirm availability, pricing and lead times in writing, and keep the written reply with your order record.
What a useful first message contains
A useful first message is short but specific. It names the category, describes the object and the task in plain terms, and lists the questions that must be answered before a quotation can be compared. It is helpful to mention the environment where the equipment will be used, the equipment already installed, and any limits on space, connection or software, because those limits often decide fit more quickly than a category name does. If you have tried an approach already, say what it showed and where it fell short; that history prevents a repeat suggestion and focuses the next reply on the unresolved point.
What happens after you inquire
After an inquiry, the useful next step is a written reply that addresses the task description point by point. Compare that reply with the checklist you sent, and follow up on any item left unanswered before discussing price or timing in detail. When the reply is complete, the remaining steps are the quotation, confirmation of the included items, and written confirmation of availability and lead times before payment. Keeping each written reply with the task description creates an order record that both sides can refer to if a detail is later questioned. This site does not promise a response time, because none has been verified; if timing matters to your project, state the date by which you need a reply in the inquiry itself.
Inquiry form

Certificates available upon request.
If you are unsure which category fits your task, describe the task first and let the category follow from it. A clear task description reaches a useful reply faster than a list of category names, and it avoids an early commitment to equipment that may not suit the object or the environment.
