KERN 317-05 Single Weight (OIML E2) — 20 g polished stainless steel button

The 317-05 is a precision single weight designed for routine calibration of laboratory and industrial balances, offering stable performance for traceable mass determinations

  • OIML class E2 certified
  • Nominal value 20 g
  • Tolerance ±0.08 mg
  • Polished stainless steel button form

Secure measurement certainty for analytical balances

The calibrated nature of this weight ensures repeatable results when verifying or adjusting sensitive weighing instruments. With OIML E2 classification and a declared tolerance of 0.08 mg, the item supports high-accuracy checks on analytical and precision balances where small deviations matter. This level of specification reduces uncertainty in processes that depend on accurate mass values, supporting quality control and compliance in laboratory and production settings. The emphasis here is on measurable reliability rather than subjective claims.

Robust construction that simplifies everyday use

Constructed from polished stainless steel, the compact button shape minimises handling contact and surface damage during transfer and storage. The finish resists corrosion and is easy to clean, which helps maintain long-term stability. The design balances durability with tactile handling: the small, rounded form is quick to position on pans while limiting the risk of contamination from fingerprints. For workshops and calibration labs, this translates into less downtime and fewer repeat checks.

Handling, traceability and calibration guidance

The nominal mass is clearly defined and suitable for traceable verification routines. For tasks requiring official traceability, a DAkkS calibration is recommended as an equivalent to the previous EC-type approvals, ensuring acceptance in many regulated applications. Due to the fine tolerance class, a protective case (etui) is advised to avoid abrasion or damage during transport and storage. The compact dimensions are compatible with standard weight sets and allow straightforward integration into calibration schedules without special fixtures.

Where this weight performs best and how to care for it

Designed for use in laboratories, testing facilities and workshops, the weight is ideal for verifying analytical balances and for spot checks in quality assurance workflows. Regular cleaning with lint-free cloths and avoiding aggressive chemicals will preserve the polished surface and measurement stability. For long-term traceability, schedule periodic recalibration according to internal quality procedures or when the weight has been subject to mechanical stress. Manufactured in Germany and supplied as a singular precision test mass, it provides consistent performance for metrological tasks.
