JY60 Piston Dead Weight Tester: High-Accuracy Pressure Calibration with Tungsten Carbide Core
The JY series piston gauge is a newly developed product manufactured in compliance with the national verification procedure JJG59-2007. Its core piston-cylinder assembly is crafted from ultra-hard, low-expansion tungsten carbide, ensuring minimal deformation and exceptional long-term stability. Utilizing isooctyl sebacate as the working medium results in superior sensitivity. These advancements make it ideal for calibrating precision pressure instruments.
