Order or request advice via Metav Werkzeuge for reliable delivery and expert support. KERN 317-110-400 Plastic weight case — for single 1 kg E2 button/compact weights The KERN 317-110-400 Plastic Weight Case is a protective storage solution designed to house a single 1 kg calibration weight in button/compact form, ensuring secure transport and organised storage for calibration equipment. Single-weight case for 1 kg E2 weights Robust plastic shell for secure transport Compact button/compact design for small weights Lightweight 0.02 kg for easy handling Preserve calibration integrity with protected storage The primary advantage of this case is the measurable preservation of the reference weight's condition. By providing a robust plastic shell and a tailored internal form for button/compact weights, contamination and mechanical impact are reduced, which helps retain the weight's calibration class (E2) and nominal value (1 kg). For workplaces handling verification and calibration tasks, this contributes directly to consistent measurement results and fewer recalibrations, supporting efficient quality control and traceability chains. Designed for efficient workshop handling and transport A compact footprint and low mass make the case especially suitable for busy workshops and mobile technicians. The compact format minimises storage space on calibration trolleys or in instrument cabinets, while the lightweight construction simplifies handling during routine checks. The practical design reduces setup time and simplifies inventory management, delivering a clear operational benefit: less time searching for the right protective container and more time conducting accurate measurements. Clear compatibility and simple identification for everyday use Compatibility is straightforward: the case is intended for single button/compact calibration weights with a nominal value of 1 kg and classification E2. The interior shape accommodates the specific geometry of these weights, preventing movement that could cause abrasion or dents. The material choice of plastic balances protection with weight savings, making it easy to carry alongside other metrology tools without adding unnecessary bulk. The KERN 317-110-400 is therefore a practical component of any calibration kit that prioritises preservation and rapid deployment.
