KERN 304-07 weights set — OIML E1 calibration set, polished stainless steel

A KERN 304-07 weights set designed for laboratory and calibration use, offering high-precision mass standards for verification of analytical and precision balances.

• OIML class E1 certified accuracy
• Nominal range 1 g–2 kg
• Polished stainless steel weights
• Knob (button) design for easy handling
• Supplied in a wooden case

High-precision accuracy for reliable calibration results

The set is certified OIML E1, the highest class for calibration weights, delivering reproducible results with minimal uncertainty. As calibration standards, these weights support traceable verification of analytical balances and precision scales, helping to maintain process control in production and laboratory environments. The classification ensures compatibility with national and international metrology requirements, simplifying audit and quality management tasks.

Robust materials that reduce maintenance and downtime

Constructed from polished stainless steel, the weights resist corrosion and surface wear, preserving their mass value over time. The knob or button design facilitates safe handling during frequent checks, reducing the risk of contamination or accidental drops. Supplied in a wooden case, the set is organised for immediate use and secure storage, which minimises handling damage and keeps the workplace tidy for quicker calibration cycles.

Clear nominal values and usability across equipment types

Covering 1 g–2 kg across the nominal values, the set supports a broad range of balances from analytical to precision laboratory instruments. The individual pieces are sized for routine verification and adjustment tasks, enabling efficient in-house checks without repeated external calibration. Built to integrate with established metrology workflows, the collection of standards maintains consistent performance for verification intervals and internal quality control.

Practical benefits for workshop and laboratory operations

Using certified mass standards reduces measurement-related rework and accelerates decision-making by providing dependable reference values. The set’s finish and form enhance handling ergonomics, while the compact case simplifies transport between workstations. For procurement and logistics, the combination of recognised KERN manufacturing quality and practical packaging supports predictable supply and reduces the need for multiple suppliers.
