- Brand： glzon
- Model： GZM
Product Essence: Mass-Based Precision Beyond Volumetric Limits
Shanghai Guangzhi Gravimetric Fillers overcome density variations with ±0.05% mass accuracy – mastering foamy detergents, aerated sauces, and shear-sensitive biologics that defeat volumetric systems. Featuring multi-cell load arrays (OIML Class 0.5), AI density compensation, and GMP/ATEX-ready builds, they achieve <0.01% giveaway while eliminating bubble errors, temperature drift, and recipe changeover waste.
