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

Robust wooden construction and a padded interior provide secure storage and transport for 50 kg single calibration weights, while a compact design and an 8.5 kg case weight support convenient handling and workshop logistics. Order the wooden case directly via Metav Werkzeuge or ask our consultants if needed. KERN 317-160-100 Wooden Case for Single Calibration Weights — Padded, for 50 kg (E1–F1) The Wooden Case 317-160-100 is a padded storage and transport case designed for single calibration weights used in laboratory and workshop calibration tasks. Padded interior for secure transport Fits KERN single calibration weights Designed for 50 kg nominal value Solid wood construction for stable storage Protecting calibrated masses and ensuring reliable handling A purpose-built transport and storage solution reduces the risk of damage to precision weights. The case’s padded interior and stable wood construction protect delicate surfaces and maintain calibration integrity during handling and transit. This protection supports consistent measurement results and reduces the need for premature recalibration, providing a measurable efficiency gain in routine metrology workflows. Clear compatibility and conformity for calibration processes Compatibility with common KERN single weights simplifies workshop organisation: the case accommodates models listed by the manufacturer for single weights in button or compact form and is intended for a 50 kg nominal value within E1–F1 accuracy classes. This clarity helps planners select the correct storage for legally relevant calibration artefacts and supports traceable, standards-compliant measurement practice. Practical handling that speeds up regular use At approximately 8.5 kg, the case offers a balance between robustness and manageability, easing movement between bench, laboratory and transport. The solid construction and internal cushioning minimise handling risk and make daily use less cumbersome, enabling technicians to focus on measurement tasks rather than protective logistics. The combination of compatibility and ergonomic design promotes faster set-up and improved workshop throughput. Built for workshop environments and precise routines Constructed from durable wood and featuring internal padding, the case is suited to workshop and laboratory settings where both precision and practical storage are required. The material choice provides dimensional stability while the internal layout secures individual weights, which helps preserve surface condition and mass accuracy across repeated use and checks.
