An in-depth analysis of technical standards, manufacturing excellence, and global infrastructure applications.
Understanding the Saybolt Universal Viscosity (SUV) and Saybolt Furol Viscosity (SFV) is critical for characterizing petroleum products and liquid asphalts at specified temperatures. Our instruments comply strictly with ASTM D88.
Modern laboratories require more than manual readings. Our systems integrate AI-driven thermal control, ensuring temperature stability within ±0.05°C, reducing human error in efflux time recording.
Whether it's AASHTO T72 or ASTM standards, our manufacturing process ensures that every Saybolt viscometer meets international regulatory benchmarks for heavy-duty civil engineering projects.
Located in the ancient tech hub of Xi'an, Xi'an Zealchon Electronic Technology Co., Ltd bridges the gap between theoretical research and practical laboratory application. With a legacy spanning over 15 years, our facility is not just a factory; it is a center of excellence supported by professors from Chang'an University and the Air Force Engineering University.
Our "Xiya" trademark isn't just a brand—it's a provincial hallmark of quality in Shaanxi. We provide "Information Gain" to our clients by offering not just a machine, but the localized expertise required to calibrate instruments for extreme environments, from the humid tropics of Southeast Asia to the high-altitude projects in the Himalayas.
In high-speed railway construction, bitumen viscosity dictates the durability of the track bed. Our Saybolt testers are optimized for In-situ testing, providing real-time data for engineers on-site in China’s massive infrastructure network.
The trend is moving toward IoT-enabled laboratories. Our latest Saybolt models feature cloud connectivity, allowing laboratory managers to monitor test progress and data integrity remotely via encrypted channels.
As the world pivots toward recycled asphalt pavement (RAP), measuring the viscosity of aged binders becomes vital. Our equipment provides the high-precision resolution needed to evaluate the effectiveness of rejuvenating agents.
Founded by specialists from Xi’an Polytechnic and Xi’an Petroleum University, our R&D team holds the top technology in civil experimental instruments.
Our series of testing instruments for asphalt and pavement have won national, ministerial, and provincial awards, filling critical gaps in the domestic and international market.
Zealchon machines are used worldwide by government agencies, commercial testing labs, and contractors. Our dedication to "Craftsman Spirit" is the cornerstone of our success.
For international buyers, procurement is not just about the price—it's about Total Cost of Ownership (TCO). Our solutions address the four pillars of global procurement:
Saybolt Universal Viscosity (SUV) is used for thinner liquids (oils), while Saybolt Furol Viscosity (SFV) is used for much thicker liquids like heavy fuel oils and bituminous materials. The Furol orifice is larger, allowing thick liquids to flow roughly ten times faster than through a Universal orifice.
Our testers use high-precision PID temperature controllers and standardized stainless steel orifices that are calibrated against primary viscosity standards. We strictly follow the ASTM D88 protocol.
Yes, as a manufacturer, we can customize the voltage (110V/220V/380V) and frequency (50Hz/60Hz) to meet the electrical standards of any country in North America, Europe, or Asia.
Typically, standard units are in stock for immediate shipment. Custom configurations for multi-tube setups or integrated digital data acquisition systems take approximately 15-30 days.
