Direct manufacturing with 10+ years of OEM/ODM experience — custom capacities, connectors, cable lengths and branding.
Send your capacity, application and annual quantity — pricing, datasheet and sample options within 12 hours on business days.
Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
The core sensor in commercial price-computing scales and kitchen scales. Low-profile metal-alloy body accepts off-center loads with little deflection.
Low capacity multiple capacity options
Battery-powered pocket balances, jewellery scales and portable weighing tools fit the WST108 into compact housings without sacrificing stability.
OIML-grade reading
Inline force feedback for medical infusion pumps, laboratory force-test fixtures and small press-in assemblies — anywhere a low-capacity accurate load read is needed.
