CORE
K3i
Industrial weighing indicator. Stainless precision. Industrial reliability
Durability & Build Quality
Constructed in AISI 304 stainless steel, internal honeycomb structure for enhanced resistance, and a backlit LCD screen
Connectivity & Integration
Equipped with RS 232-C and TTL interface
Hygienic design. Proven performance
Hygienic Design. Proven Performance.
The GRAM K3i delivers the same operational intelligence as the K3 series — now in a fully stainless steel housing designed for environments where moisture, cleaning routines, and hygiene standards demand more.
From piece counting and classification to two-speed dosing and automatic tare, K3i supports production, packaging, and quality control workflows with precision and simplicity.
Its sealed construction, intuitive navigation, and bright backlit LCD display make it ideal for operators who need fast, reliable control — even in wet or intensive-use environments.
