Description

The ZZG-301 is a classic mechanical spring balance scale from the Traditional Series, designed for hanging weighing in fish docks, fresh markets, farms, agricultural sites and logistics. Powered by a precision spring mechanism, it needs no battery, no charger and no electronics - so it works in any weather, on off-grid sites, or in wet and dusty environments where digital scales would fail. Five capacities are available - 12 kg, 25 kg, 50 kg, 100 kg and 150 kg - with scale sizes ranging from 17.5 x 3.2 cm to 34 x 4.6 cm. The anodized aluminum body is corrosion resistant and built for daily field use. A precision sliding pointer delivers instant readings, while the dual KILO / LBS scale suits both metric and imperial markets. The scale ships with a stainless steel top ring and bottom hook for quick hanging. OEM / ODM customization includes logo printing, body color (classic gold or professional black), and export carton branding. Made by Yongkang Zhezhong Weighing Apparatus Factory (Saint Fire) - Est. 1989 | 35+ Years, our 12,000 sqm factory runs 6 production lines with a monthly capacity of 100,000+ Units/Month. Stock ships in 3-5 days, bulk orders in 15-20 days. CE / RoHS / ISO 9001 certified with a 1-year warranty (extendable).
