KERN 307-14 — 10 kg OIML class E1 calibration weight, polished stainless steel

The KERN 307-14 is a single calibration weight designed for high-precision balancing and laboratory calibration, featuring a knob form for secure handling and a polished stainless-steel finish for durability and easy cleaning.

  • OIML class E1 accuracy
  • Nominal mass 10 kg
  • Polished stainless-steel knob
  • Tolerance ±5 mg

Consistent traceability for precise calibration results

The calibration mass is manufactured to OIML class E1, the standard expected in calibration laboratories where traceability and minimal uncertainty are required. The precise 10 kg nominal mass and the 5 mg tolerance mean fewer repeat measurements and clearer uncertainty budgets when recalibrating analytical and precision balances. Laboratories benefit from reliable test weights that minimise measurement drift and support accreditation demands, turning a single artefact into a stable reference for routine quality assurance.

Robust, serviceable design for everyday laboratory handling

The weight’s polished stainless steel construction combines corrosion resistance with an easy-to-clean surface, reducing contamination risk in sensitive environments. The knob form provides ergonomic handling and safer placement on pans during calibration cycles, while the compact cylindrical geometry (100×185 mm) fits a wide range of balance pans. These design choices lower handling errors and contribute to longer service life, making the weight a practical investment for busy metrology rooms and calibration services.

Simple storage and handling guidance to protect accuracy

Correct handling and storage extend calibration intervals and preserve the declared tolerance. Store the mass in a protective case recommended for high-precision weights and handle with gloves or forceps to avoid surface contaminants and mass shifts. Periodic visual inspection for damage or corrosion, combined with scheduled recalibration, keeps the mass within its OIML E1 specification and ensures ongoing confidence in measurement results.
