KERN 303-076

The 303 076 calibration weight set is built for laboratories, testing facilities, and quality control environments where accuracy is a top priority. It meets OIML class E1 requirements, which means it offers the highest precision in weight calibration. This makes it especially suitable for adjusting precision and analytical balances that demand extremely fine tolerances.

This set includes knob shaped weights ranging from 1 milligram up to 2 kilograms. The wide range allows technicians and laboratory staff to perform calibrations across different balance types, from highly sensitive instruments to medium capacity models. Each weight is made of polished stainless steel, which provides long lasting durability, protection against corrosion, and a smooth, easy to clean surface. The high quality finish also helps reduce contamination risks, an important feature in pharmaceutical and food laboratory applications.

The weights are carefully adjusted using precise polishing methods, ensuring each piece stays within the very strict tolerances required by the OIML E1 class. This guarantees consistent, repeatable calibration results, giving users confidence that their instruments are performing at the highest level of accuracy.

For safe handling and storage, the set comes in a strong aluminium case. The case is fitted with custom compartments for each weight, keeping them organised and protected against damage or loss. Its compact dimensions of 278 × 180 × 138 millimetres make it easy to transport, whether for use in fixed laboratory settings or by calibration professionals working on site.
