In the modern era of civil engineering, the Digital Asphalt Kinematic Viscometer has evolved from a simple laboratory tool into a critical instrument for infrastructure longevity. As global temperatures rise and traffic loads increase, the rheological properties of bitumen—specifically its kinematic viscosity—dictate the rutting resistance and thermal cracking behavior of asphalt pavements.
The global market is witnessing a shift toward Superpave specifications and Performance-Graded (PG) binder systems. High-quality manufacturers like Xi'an Zealchon are at the forefront, providing instrumentation that meets rigorous ASTM D2170, ASTM D445, and EN 12595 standards. These devices are essential for refineries, road construction firms, and national transportation agencies ensuring that bitumen binders maintain optimal flow characteristics during mixing and compaction.
Our viscometers utilize high-precision Pt100 platinum resistance sensors and advanced PID fuzzy logic control. This ensures a temperature stability of ±0.01°C, a prerequisite for accurate kinematic viscosity measurements as per international standards.
Replacing the human error of manual stopwatches, our digital viscometers feature infrared photoelectric sensors that detect the meniscus passage through capillary bulbs with millisecond accuracy.
Equipped with RS232/USB interfaces, our equipment supports LIMS (Laboratory Information Management Systems) integration, allowing for real-time data export and remote monitoring of test progress.
Featuring dual-layer high-temperature resistant glass baths and over-temperature protection, ensuring operator safety while maintaining high visibility for visual verification.

The "Xiya" trademark was rated as a trademark of Shaanxi Province. Under the guidance and cooperation of many professors and researchers from Chang'an University Highway College, Air Force Engineering University, and Xi'an University of Technology, we introduced technology to develop a series of professional and core technology testing instruments.
On one hand, the research team is founded by personnel from prestigious institutions which provides us with the top technology in this expertise. In addition, its research and development has accomplished a series of leading domestic and international standards, filling the gaps in similar instruments and winning ministerial and provincial awards.
Our machines are used worldwide by government agencies, commercial testing laboratories, ready-mix producers, contractors, and universities. Over the past 15 years, our customers have recognized our dedication to quality products, performance, value, and customer satisfaction which has become the cornerstone to our success.
