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

Take advantage of the aluminium construction and padded interior for reliable protection of calibration block weights up to 50 kg, combined with the trusted quality of KERN — order the aluminium-protected case directly via Metav Werkzeuge or ask our consultants if needed. Aluminium-protected case 346-090-600 — padded transport and storage case for 50 kg block weights by KERN The Aluminium-protected case 346-090-600 is a padded storage and transport solution for block weights, engineered to safeguard calibration masses up to 50 kg and suitable for calibration classes F1–M3. Aluminium housing for robust protection Padded interior for secure weight placement Designed for block weights up to 50 kg Suitable for calibration classes F1–M3 Secure transport for sensitive calibration masses The robust aluminium shell combines low weight with mechanical resistance to prevent dents or deformation during handling. The padded interior reduces shock and movement, protecting the geometry and surface integrity of sensitive calibration block weights. For calibration and verification workflows where maintaining traceability and repeatability matters, the reduced handling risk helps preserve measurement certainty and reduces the need for rework or recalibration. Precision-class compatibility for laboratory and workshop use Designed specifically for block weights and rated for calibration classes F1–M3, the case supports a range of precision applications from fine calibration to routine verification. The case’s form factor accommodates the block design and ensures that each mass remains stable during transport. This alignment with established calibration classes simplifies logistics for quality assurance departments and metrology technicians who require consistent, class-compliant storage. Efficient handling and ergonomic benefits for daily use At a lightweight of approximately 2.5 kg, the protective case is easy to manoeuvre while offering substantial protection for heavy contents. The combination of a corrosion-resistant aluminium enclosure and internal padding reduces the handling effort and extends the service life of stored weights. For workshops and calibration service providers, this means fewer damaged assets, smoother workflows and less downtime when moving calibration equipment between benches or to external labs. Durable design backed by recognised manufacturing Manufactured by KERN, the case is intended for long-term use in industrial metrology and workshop environments. The aluminium construction resists environmental influences better than many lightweight alternatives, while the padded interior secures the block form of the weights during transit. Paired with a reliable supply chain and storage practices, the case supports precise measurement routines and helps maintain the integrity of calibration artefacts over time.
