Introduction
Thank you for selecting and purchasing our K9 weight indicator, this indicator provides a compact and flexible solution for a
variety of weighing needs, especially for the wet working places.
INVENTIONS AND DESIGN PATENTED
ON17-P31351 & ON17-P20743
Double O-ring for the housing, independent sealed PCB case, transparent PC front housing and touch buttons, all give the
highest protection class till IP68 and IP69K, it can be used perfectly in the field of meat, fish process or any other food industry,
chemical materials, pharmaceutics. It can be washed by the high pressure hot water - 100 bar (1450 psi) and 80ºC, suitable for
