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
almost all harsh working environment.
PC alloy front housing and PBT back housing, give the indicator the high strength, no worry any more about the damage to it
caused by falling, crudely use of some careless workers.
It gives three options of checkweigh function, you can select the three small LED lights for checkweigh alarming, also you can set
the different backlight for different range of the weight read, or you can connect with an extra alarming light with three colors.
Various power choices:
100-240V AC Direct
9-24V DC Direct
7.4V6800mA Li-ion Battery
6V1200mA Lead-acid Battery
Various output choices:
Double RS232
4 x OUTPUT
1 x IN*
Optional Bluetooth or WiFi
* for pedal or mechanical switch, functions can be set with zero, tare or print.
