KERN 303-074 Weight set — OIML class E1, 1 mg–2 kg, polished stainless steel
The KERN 303-074 weight set is a laboratory-grade calibration kit for precision balances and quality control tasks, offering a continuous nominal range from 1 mg to 2 kg in knob-shaped weights, supplied in a protective plastic case for secure storage and handling.
- OIML class E1 accuracy
- Nominal range 1 mg–2 kg
- Polished stainless steel construction
- Milligram weights in separate plastic case
High-precision calibration that supports compliance and repeatability
Designed for the most demanding calibration tasks, the set provides OIML E1 accuracy across a broad nominal range. This class indicates suitability for calibrating analytical and microbalances where the smallest deviations matter. The continuous span from 1 mg–2 kg reduces the need for multiple disparate sets, streamlining calibration workflows and improving measurement repeatability across instruments.
Durable materials and ergonomic design minimise handling error
Manufactured in polished stainless steel, the weights resist corrosion and maintain surface integrity during repeated use. The button-shaped design facilitates safe, ergonomic handling with tweezers or gloves, reducing the risk of contamination and wear. Robust materials and an easy-to-handle form contribute to long-term stability of mass values and fewer recalibration cycles.
Organised storage for contamination control and quick access
Milligram weights (1 mg–500 mg) are stored in a separate plastic case within the main container, preventing contact and cross-contamination between classes. This organisation enables rapid selection of the required mass and preserves calibration quality. Clear separation and protective housing also support cleanroom or laboratory protocols and simplify audit-ready handling.
Reliable performance for labs and specialist workshops
Consistency in mass values supports traceable measurement processes and reduces uncertainty in quality control results. The polished family of weights is intended for professional environments where minimised measurement error translates into fewer production rejects and more predictable outcomes. Confidence in calibration quality helps maintain process stability and fosters trust in delivered parts and data.

FAQ
What balances can be calibrated with this set?
The KERN 303-074 weight set is suitable for calibrating analytical and microbalances that require OIML E1 class masses across the 1 mg–2 kg range.
What does OIML class E1 mean in practice?
OIML E1 denotes the highest level of metrological accuracy for standardised masses, making the set appropriate where minimal measurement uncertainty is essential.
How are the smallest weights protected during storage?
Milligram weights (1 mg–500 mg) are supplied in a separate plastic case within the main container to avoid contact and reduce contamination risk.
What material are the weights made from?
All weights are produced in polished stainless steel, offering corrosion resistance and long-term surface stability.
Are the weights easy to handle during calibration?
The button-shaped design enables precise handling with tweezers or gloves, reducing handling error and protecting mass surfaces.

Zubehör
Take advantage of secure, lightweight storage that protects standard weight sets up to 5 kg, compatible with calibration classes E1–M3, and designed specifically for button and compact formats; order via Metav Werkzeuge or consult our specialists for guidance. KERN 313-082-400 Plastic Case — for standard weight sets up to 5 kg, E1–M3 A KERN 313-082-400 Plastic Case engineered to protect and organise standard weight sets (button/compact form) for calibration, laboratory and workshop use Plastic case for weight sets up to 5 kg Compatible with calibration classes E1–M3 Designed for button and compact weights Lightweight construction; easy transport Faster calibration workflows with protected storage The robust plastic case provides protected, organised storage for standard weight sets, supporting nominal values from 1 mg–5 kg and calibration classes E1–M3. By keeping weights secure and clearly arranged, routine checks and calibrations require less preparation time and handling, which increases throughput in busy calibration labs and testing environments. The case’s structured capacity reduces the risk of contamination and mechanical damage, helping maintain traceability and measurement reliability. Tailored layout for compact and button weights Designed for the specific format of button and compact weights, the internal layout is optimised to hold standard pieces securely during transport and storage. The solution is explicitly not suitable for cast weights, ensuring customers select the correct storage for precision masses rather than heavy, cast components. Clear compatibility with compact designs supports orderly handling and faster identification of required nominal values during set-up and inspections. Lightweight, durable design for easy handling With a total mass of approximately 1.5 kg, the case balances protection with portability: it is light enough for frequent movement between benches or labs yet durable enough to withstand day-to-day operational stress. The plastic construction offers resistance to moisture and common workshop contaminants, contributing to long service life and fewer replacements. Reduced handling weight also lessens manual strain and simplifies logistics for mobile calibration tasks. Compliance support and workshop efficiency Built to fit recognised weight class standards, this case assists in maintaining compliant storage for precision masses and supports efficient inventory management in industrial metrology. The German origin reinforces expectations for consistent manufacturing quality. When combined with a reliable ordering partner, this storage solution helps centralise supplies and reduces procurement complexity for calibration houses and workshops.
