Website operator
This website is operated by HUBEI NINESEA IMPORT & EXPORT CO., LTD under the Specval · 思贝沃 engineering-measurement brand.
Technical status of information
Unless a page expressly identifies a value as a bench result, customer acceptance result or certified value, product values shown on this website are current engineering targets or configuration directions. They remain subject to project conditions, design review, testing, availability and a written project specification. Appearance and dimension illustrations are not manufacturing drawings.
No system-level approval claim
A measurement module is one element in a larger system. Host power, enclosure, field wiring, alarm and interlock logic, sample handling, installation, maintenance and regulatory approval may remain with other parties. A design objective such as intrinsic-safety compatibility is not a certificate. Only the written approval and its scope establish certified status.
Permitted use
You may read, link to and internally evaluate the public content for legitimate project or procurement purposes. You may not misrepresent the content, remove its qualification statements, use the Specval brand to imply endorsement, interfere with the site or attempt to access private enquiry records.
External sources
Engineering articles link to third-party primary or official sources. Those organisations control their own content. A source supports only the claim for which it is cited; it does not endorse Specval or a product.
Enquiries and commercial terms
A form submission, technical discussion, sample request or website statement does not create an order or acceptance obligation. Product scope, price, Incoterms, payment, tests, documents, warranty, intellectual property, governing law and dispute terms are established only in the relevant written quotation, order confirmation or contract.
Liability
Use professional engineering judgement and applicable laws, standards, mine rules and approved procedures. To the extent permitted by applicable law, the website is provided without a guarantee that general information is suitable for a specific process, safety function or jurisdiction.
Changes and contact
These terms may change when the website or product status changes. Last reviewed: 30 July 2026. Questions may be sent to engineer.zhao@specvaltech.com.
