KERN Milligram weight 318-01 — OIML E2, 1 mg polished stainless-steel disc The Milligram weight 318-01 is a high-precision mass standard for the calibration of analytical balances and microbalances in laboratories and quality control environments. OIML Class E2 for high precision Nominal value 1 mg, tolerance 0.006 mg Polished stainless-steel disc shape DAkkS calibration recommended Precision that meets regulatory needs for micro-mass work The polished stainless steel disc is manufactured to meet OIML Class E2, delivering a nominal mass of 1 mg with a stated tolerance of 0.006 mg. This classification indicates suitability for high-accuracy calibration tasks where traceability and conformity to international regulations are required. Explaining the term: OIML classes define permissible deviations for weights; E2 is used where analytical balances and laboratory checks demand very tight limits. The precision reduces measurement uncertainty and supports consistent results across repeated calibrations, improving process reliability in quality assurance workflows. Durable design and proper handling to protect measurement integrity Constructed from corrosion-resistant stainless steel with a polished finish, the disc form minimises surface contamination and eases cleaning. For safe handling and to avoid transfer errors, use tweezers or gloves and store the mass in a protective case; an etui is recommended due to the small nominal value and sensitivity. Regular calibration is essential: a DAkkS calibration provides national traceability and is advised for nearly all professional applications, ensuring that the mass standard retains documented conformity and can be relied upon during audits or certification procedures. Integrating the mass standard into laboratory routines Incorporating this micro-mass into calibration schedules enhances the comparability of results between instruments and sites. The combination of OIML Class E2 conformity and the polished stainless-steel construction lowers the long-term cost of rework by reducing drift and contamination-related errors.

Ideal for traceable laboratory checks and routine industrial verifications; order the milligram weight directly via Metav Werkzeuge or ask our consultants if needed. Milligram weight 318-04 — KERN calibration plate, OIML Class E2, 10 mg, polished stainless steel The Milligram weight 318-04 is a precision plate weight intended for calibrating laboratory and industrial balances where microgram-level accuracy and traceability are required OIML Class E2 accuracy Nominal value 10 mg Tolerance ±0.008 mg Polished stainless steel plate Ensure micro-scale results with OIML-class precision For applications that demand repeatable tiny-mass measurements, the combination of OIML Class E2 and a nominal 10 mg value provides a reproducible reference point. The specified 0.008 mg tolerance quantifies maximum permissible error and allows technicians to evaluate balance performance against an international standard. Using a defined reference weight reduces the need for time-consuming rework, supports quality documentation and helps maintain production throughput by ensuring instruments remain within specification. Reduced contamination and stable readings through design and material The polished stainless steel surface lowers particle adhesion and simplifies cleaning, which in turn reduces drift between calibrations. The plate form offers a compact footprint for microbalances while minimising airflow effects during handling. As a result, calibration routines are faster and less error-prone, helping to cut downtime. For environments where ambient contamination or frequent handling is likely, the material choice supports longer intervals between service cycles and contributes to consistent measurement quality. Traceability, calibration options and practical handling advice Traceability is essential for auditability and process control; therefore a DAkkS calibration is recommended, especially because statutory EG initial verification will not be possible after 30 November 2025. A DAkkS certificate provides documented equivalence for most industrial and laboratory applications and supports compliance with internal quality systems. Due to the sensitivity of milligram weights, storage in a suitable case is advised to protect the reference mass from contamination and mechanical damage. Regular visual inspection and controlled handling minimise uncertainty and prolong reliable service life. For traceable micro-scale calibration and DAkkS calibration options, contact Metav Werkzeuge to arrange supply of the KERN 318-04 or to discuss the right calibration route for the application.

Milligram weight KERN 318-05 — 20 mg OIML E2, polished stainless steel plate A Milligram weight KERN 318-05 designed for calibration of precision balances and laboratory scales, delivering traceable microgram-level performance in demanding metrology workflows OIML class E2 accuracy Nominal value 20 mg Polished stainless steel plate form Tolerance ±0.01 mg Traceable accuracy for high‑precision calibration The polished stainless steel construction and OIML E2 classification ensure a stable reference mass for sensitive instruments. The nominal 20 mg size is suited to microbalance verification where minimal drift and predictable handling are essential; the declared ±0.01 mg tolerance gives a clear specification for uncertainty budgets. For procurement and quality management, the measurable parameters support certificate-based traceability and allow integration into ISO/IEC 17025–aligned calibration plans. Robust design tailored to metrology workflows A plate-form geometry reduces edge effects during placement on pans of analytical balances, while the polished surface minimises contaminant adhesion and eases cleaning. The stainless finish is corrosion-resistant and compatible with common laboratory environments, contributing to long service intervals and reliable repeatability. Handling protocols benefit from the compact form: secure transport in a recommended case preserves accuracy and reduces the need for frequent re-calibration. Compliance, calibration and recommended use Note that EU initial verification (EG‑Ersteichung) of calibration weights will not be available from 30 November 2025; therefore a DAkkS calibration is recommended for most traceable applications. For high-accuracy records, a DAkkS certificate demonstrates conformity with national standards and supports audit requirements. The product is supplied as a precision reference mass for balance testing, routine checks and laboratory verification tasks where documented traceability and low uncertainty are required.
