High-capacity, robust, and traceability-ready
The Kern FES and FEJ series are high-capacity precision balances designed for demanding laboratory and industrial environments. With weighing capacities up to 62,000 g and readabilities down to 0.1 g, these balances combine exceptional precision with rugged performance.
The FEJ models feature internal automatic adjustment for location-independent accuracy and include user authentication and data security features. FES models offer external calibration with a fast setup program. Both models include a stainless steel IP65-protected display unit and metal housing, making them suitable for harsh conditions and cleanroom applications.
