KERN 314-07 calibration weight set – OIML Class E2, 1 g–2 kg, polished stainless steel

The KERN 314-07 is a knob-style calibration weight set intended for laboratory and industrial verification of balances and scales, covering the range from 1 g to 2 kg and supplied in a protective wooden case.

• OIML Class E2 accuracy
• Range 1 g–2 kg for versatile verification
• Polished stainless steel knob weights
• Supplied in protective wooden case

Reliable metrological accuracy for certification and routine checks

The set is specified to OIML Class E2, which ensures a level of accuracy suitable for calibration work where tight tolerances are required. Class E2 weights are commonly used in laboratories and quality assurance teams to verify the performance of analytical and precision balances; the classification indicates a defined maximum permissible error and makes compliance straightforward when documenting measurements. Using certified test weights reduces measurement uncertainty and supports traceable calibration procedures that are essential for audits and quality systems.

Durable, corrosion‑resistant construction that aids longevity

Manufactured from polished stainless steel, the knob-style masses combine surface protection with tactile handling advantages. Polishing reduces the risk of corrosion and eases cleaning after handling, while the knob design facilitates secure gripping and placement on pans without touching the weight body, minimising transfer of oils and contaminants. The material and finish contribute to long-term mass stability, which is critical when weights are employed frequently for routine verification rather than occasional reference measurements.

Practical storage and traceability for workshop and laboratory workflows

Supplied in a fitted wooden case, the set remains organised and protected during transport and storage, reducing the risk of damage or contamination that could affect mass values. The complete set covers the nominal values from 1 g–2 kg, enabling a single kit to support multiple verification tasks across small to medium-capacity balances. Secure storage supports traceability: when paired with appropriate calibration certificates and records, the set becomes a reliable foundation for documented measurement assurance within in-house or third-party calibration routines.

FAQ

What applications are suitable for this calibration weight set? The KERN 314-07 calibration weight set is suitable for laboratory verification, routine balance checks and industrial quality control where OIML Class E2 accuracy is required.

Is a calibration certificate included or available? Calibration certificates can be supplied separately; Metav Werkzeuge can advise on certificate options that pair with the KERN 314-07 set to meet internal documentation and audit requirements.

How does OIML Class E2 compare to higher or lower classes? OIML Class E2 provides tighter maximum permissible errors than general-use classes, offering enhanced precision for analytical and precision balances without moving to the most exacting reference classes reserved for primary standards.

How should the weights be handled and stored to preserve accuracy? Handle masses by the knob only, avoid touching the polished surfaces, and store the set in the fitted wooden case between uses to protect against contamination and mechanical damage to the weights.

Can this set be used for service work outside a laboratory environment? Yes; the robust polished stainless steel construction and protective wooden case make the set practical for field verification and service technicians who require transportable, traceable test weights
