1 mg–5 kg Test Weight Set Three-Point Button Stainless Steel Polished, Wooden Case - KERN

Take advantage of the combination of OIML F1 accuracy, a broad 1 mg–5 kg nominal range and durable polished stainless-steel weights for reliable verification of precision balances; order the set directly via Metav Werkzeuge or consult our advisors for technical details.

KERN 323-08 calibration weight set (OIML F1) – 1 mg–5 kg, polished stainless steel

The KERN 323-08 is a precision calibration weight set designed for verification and adjustment of laboratory and industrial scales, supplied in a protective wooden case for secure storage and transport.

• OIML F1 accuracy class
• Nominal range 1 mg–5 kg
• Polished stainless-steel weights
• Milligram weights in separate plastic case

Accurate verification for regulated balances

The set provides OIML F1 class calibration weights across a wide span from 1 mg–5 kg, enabling precise verification of balances used in laboratories, quality control and production environments. The classification ensures conformity with international standards, which aids traceability and supports routine calibration schedules. Operators benefit from predictable measurement behaviour because the set supports both small-mass checks and higher-capacity verifications without changing equipment, helping to reduce downtime and simplify compliance procedures.

Robust materials and practical handling

Each weight is manufactured from polished stainless steel, which resists corrosion and surface degradation, preserving the nominal mass over repeated handling. The button form facilitates secure gripping with tweezers or handling tools, reducing the risk of contamination and wear. Milligram weights (1 mg–500 mg) are supplied separately in a dedicated plastic case to protect their fine tolerances and simplify access during high-resolution checks. The wooden outer case provides organised storage and additional protection during transport, minimising handling damage and ensuring long-term usability.

Clear benefits for laboratory workflows

Using a single, consolidated set for a broad measurement range streamlines verification procedures and reduces the need to source multiple individual masses. The compact arrangement and clear class specification accelerate routine checks and recalibrations, improving process efficiency. For teams that document quality records, the class designation and material information make it easier to substantiate calibration evidence during audits. The calibration pack is particularly suitable for test benches, research facilities and specialist workshops where both micro-mass and kilogram-range checks are required.

Practical considerations and handling guidance

The polished finish and button geometry mean the set is best handled with appropriate tools to avoid fingerprints or contamination that can alter small masses. Store the milligram pieces in their separate plastic insert when not in use and return larger weights to their wooden slots to maintain order and accuracy. Periodic re-calibration in an accredited laboratory is recommended to preserve traceability; the set’s OIML F1 rating simplifies specification of recalibration intervals by aligning with common regulatory frameworks.
