Plastic case 347-030-400 — for individual calibration weights, 1 g–5 g, classes F1–M3 (KERN) The Plastic case 347-030-400 is a compact storage and transport solution for individual calibration weights, designed to keep knob/compact weights organised and protected in laboratories, workshops and service environments. Compact plastic case for individual weights Fits knob/compact weights 1 g–5 g Suitable for calibration classes F1–M3 Durable, lightweight storage solution Protects accuracy by preventing contamination and wear The case offers a secure place to store calibration weights so that surface contamination and handling damage are minimised, which in turn preserves measurement accuracy over time. By keeping knob and compact weights separated and secured, the storage solution reduces the need for frequent recalibration and helps maintain compliance with routine test intervals. This protective function is particularly relevant when handling sensitive classes such as F1–M3, where surface condition has a direct effect on measurement results. Lightweight plastic design for easy handling and transport Constructed from plastic, the case is both lightweight and durable, making movement between benches or job sites straightforward without adding significant bulk. Weighing approximately 0.02 kg, it supports convenient handling while providing a firm housing for individual pieces. The material choice balances protection with portability, offering a practical alternative to heavier metal cases where the primary requirement is safe short-term storage rather than long-term extreme environmental protection. Organises calibration workflows for faster selection and traceability A dedicated case reduces search times and streamlines the selection of the correct nominal weight during routine checks, improving operational efficiency in workshops and service departments. Clear organisation contributes to faster test cycles and less downtime, which in aggregate supports productivity goals. Where traceability is required, consistent storage in a defined case helps operators maintain an orderly inventory and reduces human error during weigh-ins and calibrations. Compatible with industry practice and a recognisable brand Designed for use with knob/compact weights in the 1 g–5 g range and suitable for classes F1–M3, the case aligns with common metrology practice and complements existing weight sets from established manufacturers. The KERN designation signals compatibility with professional weighing equipment; origin details indicate manufacturing standards consistent with European metrology supplies. As a simple yet effective accessory, the case supports routine maintenance of weights without introducing complex handling procedures.
