KERN 348-02 milligram weight — OIML M1, 2 mg polished stainless steel plate The KERN 348-02 is a precision milligram weight in OIML M1 class designed for traceable calibration of analytical balances and high‑precision scales. OIML M1 tolerance 0.2 mg Nominal value 2 mg Polished stainless steel plate Compact plate form for micro‑calibration Consistent measurement accuracy for laboratory workflows The milligram weight is manufactured to OIML M1 requirements and a tolerance of 0.2 mg, which provides a reliable reference point for routine checks and adjustment procedures of analytical instruments. This level of specification supports reproducible results across shift changes and between instruments, reducing process variation. The nominal value of 2 mg is suited to fine‑range calibrations where small deviations can influence analytical outcomes; using a dedicated reference weight helps maintain instrument performance and supports quality documentation. Robust materials and handling that protect the reference value A polished stainless steel surface and flat plate form minimise contamination and facilitate careful handling during placement on balance pans. The corrosion‑resistant finish preserves mass stability in laboratory environments, while the compact geometry simplifies centring on small balance pans and minimises convection effects during weighing. These design aspects contribute to lower risk of surface damage and ensure the reference value remains stable between calibrations. Calibration pathway and regulatory note for traceability From 30 November 2025, EC initial verification of test weights will no longer be possible; therefore a DAkkS calibration is recommended for continued traceability and documented accuracy. A DAkkS certificate links the reference weight to national standards and supports audit requirements in regulated laboratories and quality control departments. For tasks requiring documented conformity and long‑term reproducibility, a calibration from an accredited laboratory ensures the weight integrates seamlessly into a calibration interval plan.

Accurate weighing that keeps production consistent
Scales are measuring instruments that determine the weight, force or count of an object and are essential across workshops and production lines. From precision scales that resolve fractions of a milligram to crane scales that handle several tonnes, the right weighing equipment ensures process reliability, legal compliance and operational efficiency.
How the right scale supports your workflow
Scales convert mechanical or electronic signals into repeatable weight values; external factors such as local gravity, magnetism, air buoyancy and vibration influence the result and often require site-specific adjustment. For legally binding measurements a statutory verification is required, while routine quality assurance is achieved through documented calibration. Choosing the correct combination of measuring range and readability avoids unnecessary sensitivity and stabilises throughput.
Practical advantages you notice every day
- Fast, reproducible results that reduce rework and speed up throughput.
- Better process control through repeatability and consistent stabilisation times.
- Compliance where required: support for statutory verification and DAkkS-accredited calibration services.
- Lower downtime via robust designs for industrial environments and user-friendly tare functions.
- Versatility across applications with options such as precision scales, analytical balances, platform scales, counting scales and checkweighers.

- verification vs calibration: statutory verification required for legally relevant weighing; calibration for traceable quality assurance
- application areas: laboratory, production, warehouse, shipping, retail, gastronomy
FAQ
What does readability (d) mean for scales?
Readability is the smallest weight increment a scale displays. For precision scales, a smaller readability gives finer resolution but increases sensitivity to draughts and vibration.
What is the difference between accuracy and repeatability?
Accuracy describes how close a measured value is to the true value; repeatability describes how consistently a scale returns the same result under identical conditions. Both matter, but repeatability is often decisive for stable production processes.
When do I need a verified (statutory) scale?
A verified scale is required whenever weight determines legal transactions, for example sales by weight. For internal quality control, a documented calibration is typically sufficient.
Why does my scale show fluctuating values despite correct operation?
Fluctuations are often caused by environmental factors: air draught, nearby vibration, temperature changes or an unstable support. Site selection and appropriate housing or wind protection reduce this effect.
