KERN 303-06 – Weight set (OIML Class E1, 1 mg–1 kg)

A KERN 303-06 weight set designed for laboratory calibration and verification tasks, offering high-precision masses in knob form from 1 mg up to 1 kg and supplied in a wooden case.

• OIML Class E1 accuracy
• Nominal range 1 mg–1 kg
• Polished stainless-steel masses
• Wooden case with plastic insert

Reduce measurement uncertainty with high-precision standards

The set delivers OIML Class E1 accuracy, making it suitable where minimal measurement uncertainty is essential for calibration labs and precision workshops. Each mass in the range 1 mg–1 kg is manufactured to tight tolerances, helping to maintain traceable results and reproducible readings on analytical balances. By using high-accuracy mass standards, measurement deviations are reduced, which directly improves process control and conformity with quality systems.

Practical design for safe handling and organised workflows

Knob-shaped masses allow secure handling during transfer to balances, while the polished stainless-steel finish resists surface contamination and eases cleaning. The milligram group is stored separately in a plastic insert inside the wooden case, preventing cross-contact between fine masses and heavier pieces. This arrangement supports quick set-up for calibration procedures and reduces the risk of accidental damage during routine use, improving efficiency in repeat verifications.

Durable materials that support long-term stability

Constructed from polished stainless steel, the set resists corrosion and retains stable mass values under normal laboratory conditions. The wooden case provides robust protection during storage and transport, and the separate plastic compartment for milligram weights offers additional environmental isolation. Such material choices extend the service life of the masses and reduce the need for frequent replacement, contributing to lower total cost of ownership over time.

Clear traceability and suitability for calibrations

The masses are supplied as a complete kit intended for reference and verification tasks in weight metrology. Their designation as OIML Class E1 indicates suitability for high-level calibration work and for calibrating other standards used in critical measurement chains. For users with limited metrology experience, this means the set can be integrated into a traceable calibration workflow with predictable performance, backed by the consistency typical of professional mass standards.

FAQ

What accuracy class does this weight set have?
The set is certified to OIML Class E1, indicating high-precision suitability for calibration laboratories and reference mass applications.

Which mass values are included in the set?
The kit comprises masses covering the nominal range 1 mg–1 kg, arranged to support stepwise calibration and verification tasks across analytical and precision balances.

How are the smallest weights protected during storage?
Milligram weights are supplied in a separate plastic insert within the wooden case to prevent contact with larger masses and to maintain cleanliness and stability.

Is the KERN 303-06 suitable for routine balance calibration?
Yes, the KERN 303-06 weight set is designed for calibration and verification workflows where E1 accuracy is required, helping to ensure traceable and reproducible results.

What materials are the masses made from and how should they be maintained?
Masses are made of polished stainless steel; periodic gentle cleaning with a lint-free cloth and handling with gloves preserves surface condition and mass stability.
