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.
