About Us
Shanghai Changji Geological Instrument Company, formerly known as the Shanghai Geology Factory, is a China-based petroleum instrument and highway instrument manufacturer. Since our beginning in 1998, we have been dedicated to the research and development of petroleum testing instruments and highway material testing equipment. To stay competitive in the market, we continue to offer new products every year. In addition, we produce our products according to ASIM, IP, GB, and related international standards, thus allowing us to satisfy the demands of global customers.

Products
Our products fall into four main categories and are available in over 150 varieties. Having the advantages of high accuracy, easy operation, and great durability, our products are widely used in the oil and gas industry and petrochemical, highway construction, geological exploration, and other fields.
Within the petroleum testing equipment section, we have a wide range of freezing point testers, dropping point testers, sulphur content testers, density testers, water content testers, distillation testers, and so on. These products are used to determine things such as the viscosity, water content, distillation, carbon residue, cloud point, heat value, flash point etc. of lubricating oil, fuel oil, mineral oil, solvent oil, transformer oil, turbine oil, crude oil, and more.
In the highway material testing equipment section, we have products such as slurry testers, wheel track testers, mixture stirrers, asphalt content testers, softening point testers, wax content testers, and standard viscometers. All these instruments are designed and developed with highest level of precision to meet the requirements of a variety of industries and their respective testing procedures.
Under the geological instrument section, we supply inclinometers, concrete pile detection systems, logging winches, well logging instruments, and calipers.
Our laboratory instrument section contains oxygen bomb calorimeters, rotational viscometers, water baths, and electrical hygrometers. These products have found applications in many industries, such as thermal power, metallurgy, cement, petrochemical, and highway construction.

Quality and Cost Control
As an experienced petroleum instrument and highway instrument manufacturer, we know how to produce a high-quality, low-priced product. By continuously supervising the production processes, we ensure that each instrument meets quality requirements. To keep our prices down, we adopt advanced technology from American and European countries, use sophisticated production and testing equipment, and employ a team of highly trained and experienced engineers. As a result, we have passed the ISO9001:2000 certification, and our products have achieved an internationally advanced level in terms of quality and technical performance.
