KERN & SOHN: Your Reliable Partner for Measuring and Weighing Technology
For more than 180 years, the KERN brand, based in Balingen, Germany, has stood for maximum precision and reliability in measuring and weighing technology. In 1844, company founder Gottlieb Kern developed the most precise balances of his time – a standard that continues to shape the ongoing development of our family-owned company today. Our portfolio now includes more than 5,000 products, including scales, balances, test weights, microscopes and measuring instruments for professional use in laboratories, medical environments, industry and retail. This range is complemented by calibration and testing services as well as software solutions. The KERN IoT-Line stands for an innovative product line of connected, intelligent weighing systems designed for seamless integration into digital systems.


Definition of the KERN IoT-Line:
KERN IoT-Line balances – smart weighing solutions for the digital future:
With the KERN IoT-Line, all our IoT scales become true smart weighing solutions for the digital future. Networked via interfaces such as RS-232, USB, Ethernet, Wi-Fi, Bluetooth, and analogue connections, these universal connectivity weighing scales enable seamless integration into a wide variety of digital environments and offer advanced bidirectional communication.
More than just scales, they function as compact industrial PCs. Their exceptional ability for universal data connection and two-way communication sets new standards in the industry. Bidirectionality means KERN IoT scales can not only output a wide range of data types, but also simultaneously receive external commands and input data, such as tare weights, directly from external systems — enabling easy integration into ERP systems, production management, quality control, or medical patient management systems.
All functions are clearly described in the standardized KERN Communication Protocol (KCP) (see interface protocol), compatible with MT-SICS, and available via all KUP (KERN Universal Port) and KUM (KERN Universal Module) interfaces.
Integrate your IoT scale into your target system:
ERP systems
Production management systems
Quality control systems
Patient management systems
MS Excel

How does the weighing data get into your target system?
We offer three options for capturing and processing transaction data for your target system:
KERN Communication Protocol KCP: The scale is connected "directly" to the target system. The target system requests the weighing result via the KCP protocol.
KERN Software BalanceConnection: The application records weighing data, adds date, time, user, etc. to it if necessary and forwards it to the target system via key simulation, or saves the data directly in an Excel, CSV oder log file.
KERN Software EasyTouch: The application combines weighing data with a variety of object data and thus generates process results such as counting results, recipe data, an test reports, and it stores them in a tamper-proof central database, which can then be further processed in the target system.

KERN Universal Port (KUP)(KUP) in combination with the KERN Universal Module (KUM)
The KERN Universal Port (KUP) enables the connection of external KUP interface adapters, such as RS-232, USB, Bluetooth, Wi-Fi, analog, Ethernet, etc.
The outstanding advantage here is that the KUP interface adapters are simply plugged on, i.e. interfaces can be conveniently replaced and retrofitted without opening the scale housing or any complicated installation.
The interface adapters enable convenient transfer of weighing data to networks, PCs, smartphones, tablets, laptops, printers, etc. In addition, control commands and data inputs can also be sent to the scale via the connected devices.
The KERN Universal Module (KUM) is already installed in the operating terminal of platform, floor and pallet scales. Especially for use in moisture or dust-protected areas up to IP68, a connection via Bluetooth or Wi-Fi is recommended to avoid opening the terminal.
Tip: With the KERN KUP-13 extension box, up to three interfaces can be operated in parallel on the scale.
What interfaces do the KERN IoT scales have?
KERN IoT balances offer universal connectivity thanks to the flexible options with KUP (KERN Universal Port) and KUM (KERN Universal Module). These enable seamless integration into a wide range of systems and applications.
KCP: The data highway of the scale
The KERN Communication Protocol (KCP) enables the scale to be queried and remotely controlled via computer or CRM/ERP systems. The KCP is a standardized interface command set for KERN scales and other measuring instruments, which allows all relevant parameters and device functions to be accessed and controlled. KERN models from the IoT-line with KCP can therefore be easily connected to computers, industrial control systems, and other digital systems. The KERN Communication Protocol is largely compatible with the MT-SICS protocol. The KCP is available via all KUPs and KUMs.
KCP – Export ("Outbound")
stable and immediate weight
live transmission of the weights
storage of gross, tare and net weights, stability feature, date, time, etc., in the tamper-proof alibi memory
output of the weight in all available units, percent, and a free factor
output of the weight in items (piece-counting function)
output of the weight at freely definable intervals
and much more
KCP – Import ("Inbound")
access to the central device data
setup of or access to an individual device ID number
setting or querying of a tare value (pre-tare value) from an external source
setting or querying of a tare value (pre-tare value) from an external source
setting of the reference value in the scale to output the weight as a percentage or in items
setting of a network address for the scale (IP) – also for Wi-Fi
and much more
