KERN 307-16 calibration weight — OIML Class E1, 50 kg, polished stainless steel

The KERN 307-16 is a knob-shaped calibration weight designed for laboratory and industrial scale verification where repeatable, certified mass values are required

  • OIML class E1 for highest accuracy
  • 50 kg nominal mass, precision 25 mg
  • Polished stainless steel, knob design

Laboratory-grade accuracy that reduces calibration uncertainty

The OIML Class E1 designation indicates the weight meets the strictest international tolerances for reference masses, suitable for primary checks and accredited verification routines. With a nominal mass of 50 kg and a declared tolerance of 25 mg, this reference mass supports traceable adjustments and uncertainty budgets in high-precision metrology. The specification minimises rework and reduces the frequency of repeat measurements, which contributes directly to production efficiency and audit readiness.

Robust design for safe handling and long-term stability

Manufactured from polished stainless steel, the weight combines corrosion resistance with a finish that eases routine cleaning and prevents contamination of delicate balance pans. The knob shape provides a secure grip for controlled placement and removal, lowering the risk of handling error and surface damage. These design choices extend service life and preserve calibration integrity, so verification intervals can be planned with confidence rather than constant corrective work.

Seamless integration into quality systems and calibration workflows

This reference mass is prepared for immediate use in laboratory and industrial environments, supporting documented calibration procedures and ISO-compliant traceability chains. The robust material and exacting tolerance simplify the establishment of measurement uncertainty and support accredited processes. For transport and storage, a protective case is recommended because the high-accuracy class benefits from minimal handling and stable environmental conditions; Metav Werkzeuge offers suitable accessories to complete a reliable calibration routine.

Choose the KERN 307-16 for uncompromised reference accuracy and contact Metav Werkzeuge in Emmerich for accessory recommendations and secure, reliable supply from our central quality filter.

FAQ

What does OIML Class E1 mean for measurement tasks?
OIML Class E1 denotes the highest international tolerance class for reference masses; the KERN 307-16 meets these limits and is therefore suitable for primary verification and calibration where minimal uncertainty is required.

Is a protective case necessary for this weight?
Yes — due to the very fine tolerance, a protective case is strongly recommended to avoid contamination and mechanical damage; Metav Werkzeuge lists suitable etuis in the accessories section.

What is the declared accuracy of the 50 kg weight?
The KERN 307-16 has a nominal mass of 50 kg with a declared tolerance of 25 mg, enabling tight uncertainty control in calibration procedures.

Can this weight be used in accredited calibration laboratories?
The combination of OIML Class E1 specification and polished stainless construction makes this reference mass appropriate for use in accredited routines and documentation that require traceable reference standards.

Pair Leather/Cotton Gloves For Protecting Test Weights From Finger Oils And Moisture, Ideal For ≥2kg - KERN

Preserve measurement integrity by using a lightweight leather/cotton glove pair that shields calibration weights from finger oils and moisture, extending their service life and reducing cleaning intervals; order directly via Metav Werkzeuge or consult our specialists for application advice. KERN 317-290 gloves — Leather/Cotton protection for calibration weights The KERN 317-290 gloves are designed to protect calibration weights from contamination and moisture during handling in workshops and laboratories Leather-lined cotton construction for gentle handling Protects weights from finger oils and moisture Suitable for calibration weights from 2 kg Lightweight design, compact storage Preserve calibration accuracy with gentle handling Handling mass standards without protection risks surface contamination that affects repeatability and traceability. The KERN 317-290 glove pair combines leather/cotton materials to provide a soft, low-abrasion contact surface that significantly reduces transfer of finger oils and deposits. This gentle barrier supports consistent readings by limiting the need for frequent cleaning, which in turn helps to maintain calibration schedules and reduces downtime for precision equipment. Streamline daily workflows in workshop and lab A reliable handling solution simplifies routine procedures: the gloves are optimised for daily handling of weights and are particularly suited to masses from 2 kg upward, where manual manipulation is common. Their lightweight construction allows extended wear without fatigue, improving operator comfort and process throughput. By preventing contaminant transfer, the gloves help to keep weighing stations operational and reduce the frequency of weight surface maintenance. Durable solution from a trusted precision partner Selecting accessories from established manufacturers contributes to consistent quality across the supply chain. These gloves are supplied by KERN and distributed via Metav Werkzeuge, whose service model acts as a quality filter for European workshops. The combination of robust materials and proven distribution practices supports long-term reliability and a steady supply of precision accessories for industry and trade.

The gloves are intended for use with calibration weights from 2 kg and above; for smaller masses alternative handling tools may be recommended. How do the gloves protect the weights? The leather/cotton construction of the KERN 317-290 minimises direct skin contact and reduces transfer of oils and moisture that can alter weight surfaces. Can the gloves be cleaned or reused? The gloves are designed for repeated use; follow manufacturer care instructions to maintain material performance and surface cleanliness. Will using the gloves reduce the need to clean weights? Regular use of protective gloves lowers contamination rates and consequently reduces the frequency of weight cleaning and maintenance. Who supplies these gloves through Metav? The gloves are supplied by KERN and distributed via Metav Werkzeuge (SKU 317-290) as part of precision handling accessories. KERN — address and direct contact details not provided by the supplier
