Multifunctional Precision Balances with Advanced Weighing Cell Technology
The KERN PBS and PBJ series are robust, high-precision laboratory balances designed for versatility, accuracy, and reliability. With advanced single-cell weighing technology and either internal (PBJ) or external (PBS) calibration, these balances are ideal for professional laboratory use, quality control, and process assurance applications.
The PBJ models include internal automatic adjustment triggered by time or temperature, while PBS models offer external calibration through the CAL program. All balances feature rugged metal housing, fast stabilization times (~3 seconds), high corner load performance, and optional verification and accessories.
