1 mg–500 mg Weight Set Three-Point Polished Stainless Steel Plates, Plastic Case, OIML Class M1 - 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.
