HPC-Ax
Hoko HPC-Ax Series | High-Precision Automatic Spring Tester
The Ultimate Choice Trusted by Global Spring Manufacturers. The Japan-made Hoko HPC-Ax Series is a high-precision automatic tension and compression spring tester designed for those who refuse to compromise on quality. Unlike conventional testers with moving sensors, the HPC-Ax features a fixed-sensor architecture that meets the rigorous JIS B7738 Grade 0.5 standards. Trusted by industry giants like Panasonic and Fuji Electric, it provides the stability and precision required for high-end manufacturing.
Features
Industrial-Grade Stability & Protection Equipped with a dual-protection system (Hardware & Software) for the load cell, the HPC-Ax is built for longevity. Its ultra-stable mechanism results in an exceptionally high uptime with minimal maintenance required.
Smart Windows 10 Interface Experience seamless automation. Effortlessly measure Spring Constant (K-value), Free Length, Initial Tension, and Solid Length. The Win10-based system allows for easy operation via touchscreen or mouse, just like a standard PC.
Visual Error-Proofing (Poka-Yoke) To prevent operational errors, the GUI automatically changes background colors based on the test mode:
Grey for Compression and Green for Tension. ,This intuitive visual guide protects your load cell from accidental damage.

Dual-Range High-Resolution Sensing The system intelligently toggles between High and Low (1/10) load ranges, ensuring delicate resolution for small springs and robust power for larger ones, all within a single machine.
Digital Asset Management Store unlimited test conditions and results directly to the hard drive or via USB. All data is compatible with MS Excel for advanced Cp/CpK statistical analysis..
Zero-Downtime Software Updates Software upgrades are simpler than ever. Receive updates via E-mail, download, and paste—no technician site visit required, saving you time and service costs.
-All-in-One Type: Features a built-in touchscreen PC for a compact, space-saving footprint.
-Economic U-Type: Connects via USB to any desktop or laptop, offering maximum deployment flexibility at a competitive price.
