Features and Benefits

High Capacity and High Precision - Two in One FZ series attains high capacity and high precision in single unit. With FZ 300K1GF model you can measure up to 300 kg with 1 g readability, which satisfies two demands in single unit, high capacity and high resolution. Unique technology "tuning-fork" sensor enables "two-in-one" feature. This unique technology also ensures excellent weighing performance and long-term stability even in tough condition
Reliable  Measurement For Every Process In Manufacturing FZ series helps your daily weighing operation in every process in manufacturing line. With weighing range from 620 g to 300 kg and minimum read-out 1mg, FZ can cover every process, in-bound material control, production, inspection and out-bound control, etc...
Selectable Indicator You can choose one of two indicators, i02 type and i03 type. i03 type has two sub-displays in which two additional information can be indicated (tare weight, gross weight, lower and upper limit, etc..). It make weighing operation easier and more comfortable
IP Protection, Easy To Clean All models in FZ series have IP protection (rating 65) which allows FZ to be used in tough environment. After daily operation you can wash FZ with water and keep balance in clean condition
