KERN 303-044 weight set (OIML Class E1, 1 mg–200 g)
The KERN 303-044 is a precision weight set designed for the calibration and verification of analytical and precision balances in laboratories and production environments.
- OIML Class E1 accuracy for traceable calibration
- Mass range 1 mg–200 g in knob form
- Polished stainless steel for corrosion resistance
- Separate plastic tray for milligram weights
- Compact plastic case for secure storage
Calibrate with certified accuracy for consistent results
The set provides OIML Class E1 accuracy across a wide span from 1 mg–200 g, making it suitable for the most demanding calibration tasks. Class E1 designation ensures the masses meet strict international tolerances for high-precision applications; this supports documented traceability and reduces measurement uncertainty when verifying analytical balances. The combination of fine graduations and certified accuracy streamlines conformity checks and quality assurance processes.
Simple handling and secure storage to protect mass standards
Knob-shaped masses and a dedicated tray for the milligram range simplify handling during routine calibrations, reducing handling time and contamination risk. The entire assortment is supplied in a robust plastic case, with the smallest milligram weights housed in a separate plastic etui to prevent mixing and damage. These design elements protect the integrity of the mass standards and make transport between calibration stations straightforward.
Durable materials that maintain long-term stability
Manufactured from polished stainless steel, the masses resist corrosion and retain surface quality under normal laboratory conditions. Polished finish minimises surface contamination and eases cleaning without aggressive treatments. Material stability contributes to consistent mass values over time, supporting reliable performance when used for periodic verifications or routine checks in production and metrology departments.
Designed for laboratory and industrial calibration workflows
The set suits a range of applications where high-precision masses are required: instrument qualification, routine balance checks and internal quality control. The graded distribution of masses enables efficient stepwise checks across the 1 mg–200 g span, while the knob form supports confident manipulation with forceps or gloved hands. Specified features focus on operational efficiency and measurement confidence rather than aesthetic additions.

Zubehör
Take advantage of durable, lightweight storage and organised inserts to keep calibration weights safe and accessible; the compact design supports routine handling and workshop transport. Order the plastic case directly via Metav Werkzeuge or ask our consultants if needed. Plastic case KERN 313-052-400 – Carrying case for standard calibration weight sets, up to 500 g The Plastic case KERN 313-052-400 is a compact carrying solution for standard calibration weight sets, providing organised storage and protection for weights used in precision metrology. Plastic case for standard weight sets up to 500 g Designed for weight classes E1 to M3 Compact, lightweight design for workshop transport Compatible with button/compact weight formats Secure storage that preserves calibration accuracy The robust plastic construction provides a protective outer shell that shields calibration weights from dust, knocks and moisture during storage and transit. Inside, the layout is tailored for standard subdivision sets so that each mass is held securely; this reduces the risk of surface damage and contamination that can affect measurement results. Conserving the surface integrity of calibration masses supports repeatable weighing and helps maintain traceability between calibration intervals. Organised layout for efficient handling and traceability A clearly arranged internal layout enables quick identification and removal of individual masses, which speeds up routine checks and decreases handling time. The case is specified for weight classes E1–M3 and nominal values up to 500 g, matching common calibration procedures in laboratories and workshops. By keeping sets together in a dedicated container, record-keeping and procedural compliance are simplified, which supports quality systems and audit readiness. Workshop-ready: portable, lightweight and practical With a low own weight of 0.35 kg, the case is easy to carry between bench, calibration station and storage shelf. The compact format reduces occupied space on the workbench and is convenient for mobile service technicians who require a reliable transport solution. The material resists routine workshop wear and can be wiped clean, so maintenance is straightforward and no specialist care is required to keep the case operational. Clear scope of use and compatibility guidance The design caters specifically to button/compact mass formats and standard weight sets; it is not suitable for cast weights or atypical mass geometries. This distinction matters because cast masses often require bespoke recesses or heavier-duty containment. If there is uncertainty about compatibility with a particular set, the case’s intended scope—standard subdivision, E1 to M3, up to 500 g—should be checked before purchase to ensure correct fit and continued measurement reliability.

The case is specified for nominal values up to 500 g; weights above this range are not covered by the internal layout and may not be held securely. Can the case be used for different weight classes? Yes, the container is designed for weight classes E1 to M3, supporting the common precision classes used in calibration laboratories. Does the case protect weights during transport? The plastic shell and organised recesses provide protection against shocks and contamination during routine transport and handling. Are cast weights suitable for storage in this case? No, the case is not suitable for cast weights; those typically require specific accommodation due to different shapes and higher mass. Who supplies this product and where is it shipped from? The product is supplied by KERN and can be ordered via Metav Werkzeuge; stock is distributed from Emmerich for delivery across Europe. KERN, Germany — Contact: not provided
