1 mg–500 mg Weight Set Three-Point E2 Polished Stainless Steel Plates, Plastic Case - KERN

Benefit from robust plastic construction, compatibility with single nominal values 1 mg–500 mg and secure organisation for calibration weights of classes E1–M2, ensuring reliable storage and easy handling. Order the case directly via Metav Werkzeuge or ask our consultants if needed. KERN 347-009-400 Plastic Case for Single Calibration Weights – for 1 mg–500 mg, E1–M2 The KERN 347-009-400 is a compact plastic case designed to protect and organise single calibration weights for laboratories, service engineers and workshop calibration tasks. Compact plastic case for calibration weights Fits single weights from 1 mg to 500 mg Compatible with classes E1 to M2 Lightweight at approx. 0.02 kg Protects precision weights during storage and transport The case provides secure storage for individual calibration weights, reducing the risk of contamination and handling damage that can alter mass values. The internal layout is adapted for button/compact designs commonly used in calibration sets; this keeps each weight separated and stable during transport. By using a dedicated enclosure made from durable plastic, routine handling becomes more predictable and safer for sensitive measurement artefacts. Ensures compatibility with recognised accuracy classes Designed for nominal values from 1 mg–500 mg, the enclosure supports weights used across common accuracy classes E1–M2, which makes it suitable for laboratory checks and field calibration. For readers less familiar with classes: E1 and M2 denote standardised tolerance ranges used in legal and laboratory metrology; storing weights in the correct case helps maintain traceability and reduces the chance of cross-contamination that could compromise conformity checks. Lightweight, compact design for efficient workflow At roughly 0.02 kg, the case contributes negligible additional mass while offering a compact footprint for bench or toolbox storage. The plastic construction balances low weight with sufficient rigidity to protect contents, enabling technicians to carry sets between site visits without bulky packaging. The space-saving profile also assists in organised inventory management, simplifying quick selection and return of individual weights during calibration routines. Practical benefits for workshops and calibration services For calibration laboratories, service teams and quality departments, a purpose-built case streamlines handling and reduces downtime caused by misplaced or contaminated weights. The product supports better operational consistency by keeping single calibration weights in order and immediately accessible, which translates into fewer interruptions during measurement tasks and a smoother calibration workflow.

Combining absolute micro-level accuracy with a robust stainless steel construction and OIML Class E2 conformity, the weight supports repeatable calibration results and reliable traceability. Order the KERN 318-01 via Metav Werkzeuge or consult our specialists for calibration and handling advice. 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. For procurement and logistic certainty, Metav Werkzeuge supplies the mass with transparent handling and delivery from Emmerich; relying on a supplier with an extensive product range and documented experience supports uninterrupted operation in laboratories and production control points.

Yes, the disc is intended for analytical and microbalance verification; regular checks and documented DAkkS calibration keep results traceable and auditable for routine quality control. Is special handling required to avoid measurement errors? Handle the mass with tweezers or gloves and store it in a protective etui to prevent contamination and mass transfer; the polished stainless-steel surface reduces adherence of residues. Is DAkkS calibration necessary for this product? A DAkkS calibration is recommended for almost all professional applications and provides national traceability equivalent for regulatory and laboratory requirements. Will the weight remain available for EC first verification after November 2025? EC first verification for weights will not be possible from 30 November 2025; for ongoing professional use, the KERN 318-01 should be paired with a DAkkS calibration as advised.

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.
