quarrz.com is the official website for the quarrz “科思” brand operated by Hangzhou Jinmai Instrument Co., Ltd. It is positioned as a manufacturer showcase site for density measurement instruments. Its product lineup centers on electronic density meters, solid density meters, liquid density meters, specific gravity meters, concentration meters, and precious metal purity testers, serving industries and use cases such as rubber and plastics, metal alloys, powder metallurgy, ceramics, minerals and jewelry, chemical liquids, university laboratories, and quality inspection organizations.
The site organizes products into “Solid Series,” “Liquid Series,” and “Other Series.” The solid category covers density testing for materials such as rubber and plastics, tires, glass, polymers, metal alloys, cemented carbide, powders, ceramics, rocks, jewelry, and wood. The liquid category includes testing for liquid density, Baumé degree, concentration, sugar content, Plato degree, petroleum API gravity, and water glass modulus. The other category includes multifunctional solid-liquid-powder all-in-one machines and precious metal purity/content testers. The site also provides company news, industry information, FAQs, and some customer cases to support product selection and build trust.
No public pricing, complete model parameter tables, or online ordering entry points were found in the crawled content. Purchasing appears to be mainly inquiry-based. Users need to confirm specific model, measurement range, accuracy, configuration, lead time, warranty, invoice, and other details via phone, online consultation, or WeChat customer service.
The main strengths are its detailed coverage of application scenarios, especially for density testing across materials industries; customer cases include universities, companies, and testing institutions, which improves credibility; and contact information is clear, making it suitable for traditional B2B procurement communication. The drawbacks are that page content is somewhat repetitive, while product parameters, testing standards, accuracy grades, certificates, and after-sales policies are not presented systematically enough. The lack of pricing transparency and document download options also means professional buyers will still need follow-up communication for verification.
It is suitable for manufacturing R&D, quality control, laboratories, third-party testing organizations, and buyers who need rapid testing of density, specific gravity, liquid concentration, or precious metal purity. If you require highly standardized specifications, complete international certifications, or automated data integration capabilities, it is advisable to request further technical documentation and compare it with similar brands.
This is the official website of a Chinese company, with a Chinese-language interface and domestic contact channels, and it can usually be accessed directly from within China. Overall, it is a traditional industrial instrument website, prioritizing practical information over a modern digital experience.
