Located in the Xi'an High-Tech Zone, covering 7,500 sqm. We have evolved from a local manufacturer to a global leader in geotechnical and asphalt testing instruments.
In partnership with Chang'an University and Xi'an University of Technology, our R&D team integrates top-tier academic research into every hardware solution.
Equipped with advanced machining centers, CNC lathes, and argon arc welding, ensuring every Saybolt orifice and bath is machined to micron-level tolerance.
Our instruments are the trusted choice for government agencies, commercial labs, and international contractors across five continents.
The "Xiya" trademark is a symbol of quality in Shaanxi Province, recognized for filling technical gaps in structural and geotechnical testing.

Ensuring the asphalt mix has the correct pumpability and sprayability for large-scale highway paving projects.
Utilized at the end of the distillation process to grade bitumen according to international penetration and viscosity indices.
University labs use our equipment to develop new "Smart Asphalts" that react to climate changes, requiring high-repeatability testing.
Xi'an Zealchon provides more than just hardware. We offer a Global Compliance Guarantee. Every Saybolt tester shipped to the EU, North America, or Southeast Asia is calibrated against localized standards (ASTM vs EN). Our technical support team in China works in tandem with local distributors to provide 24/7 troubleshooting and maintenance.
Our R&D is currently moving toward AI-Integrated Viscosity Analysis. Future iterations of our testers will include cloud-based predictive modeling, allowing labs to predict pavement aging based on initial viscosity readings. By integrating semiconductor laser technology (one of our core specialties), we are achieving non-contact measurement thresholds never before seen in civil engineering.
