Weight set KERN 303-09 — OIML E1 precision, 1 mg–10 kg, polished stainless steel

The Weight set KERN 303-09 is a precision calibration set designed for laboratory and industrial balances, offering OIML E1 accuracy across a 1 mg–10 kg range and supplied in a wooden presentation case.

• OIML E1 accuracy for laboratory calibration
• Range 1 mg–10 kg in knob-shaped weights
• Polished stainless steel for corrosion resistance
• Supplied in wooden case with plastic insert

Certified accuracy for traceable calibration

Calibration tasks demand repeatable, documented results. The set complies with OIML E1, the highest international class for calibration masses, ensuring the highest level of measurement certainty for sensitive laboratory balances. The certified 1 mg–10 kg range covers fine microgram-level control up to larger standard weights, reducing the need for multiple kits and streamlining calibration workflows. This level of precision supports compliance routines and helps avoid costly measurement deviations.

Robust design and careful storage extend service life

A polished stainless steel finish offers inherent corrosion resistance and smooth surfaces that are easy to clean without affecting mass values. The weights are manufactured in a knob-shaped design for safer handling and repeatable placement on pans. Milligram weights are stored separately in a dedicated plastic insert inside the wooden case, limiting contamination and mechanical contact. Together, these design choices lower maintenance effort and preserve metrological performance over time.

Built for laboratories and quality assurance environments

The kit is suitable for calibration tasks in metrology labs, quality control departments and specialised workshops where tight tolerances are critical. Manufactured by KERN in Germany, the set is intended for organisations that require traceable references and stable measurement baselines. Using a single, certified set reduces uncertainty propagation through production processes and supports reliable decision-making in inspection and testing routines.

FAQ

What accuracy class does this weight set meet?
The KERN 303-09 weight set meets OIML E1 requirements, providing the highest accuracy class for laboratory calibration masses.

Is the set suitable for use in a calibration laboratory?
Yes. The calibration set from KERN is designed specifically for laboratory and quality-control use, covering the 1 mg–10 kg range with E1 conformity.

How are the milligram weights protected during transport?
Milligram weights are housed in a separate plastic insert within the wooden case to prevent contact and contamination during handling and transport.

What material are the masses made from and how should they be cleaned?
The masses are made from polished stainless steel; gentle cleaning with a lint-free cloth or appropriate laboratory cleaning solution is recommended to avoid altering mass values.

Can this set replace multiple smaller kits for a calibration schedule?
The broad 1 mg–10 kg range reduces the need for several separate kits, streamlining calibration routines and inventory while maintaining traceability.
