Aluminium-protected Case 313-070-600 — KERN; for 1 mg–2 kg, E1–M1 The Aluminium-protected Case 313-070-600 is designed to protect and organise standard calibration weight sets from 1 mg to 2 kg, delivering secure storage and easy handling in laboratory and workshop environments. Aluminium protection for secure storage Compatible with E1–M1 calibration classes Accommodates 1 mg–2 kg weight range Designed for button/compact weight sets Protection tailored to metrology needs The case is constructed from aluminium, providing a corrosion-resistant and impact-resistant shell that reduces the risk of contamination and mechanical damage during transport or storage. For precision weights, surface integrity and a dust-free environment are essential; the sturdy housing preserves the calibration condition of weights used in high-accuracy applications. By combining a rigid outer shell with an interior layout that minimises movement, the system supports long-term measurement reliability and reduces the need for frequent recalibration. Organised layout to speed up calibration workflows A clear internal arrangement for button/compact weights streamlines the preparation and execution of calibration procedures. The defined compartments allow quick identification and retrieval of the required nominal values, saving time in routine checks and audit preparations. Reduced handling lowers the chance of fingerprints or particles affecting mass standards, which in turn supports consistent results and accelerates workflow in both metrology laboratories and service departments. Built for longevity and practical handling Lightweight yet robust construction balances portability with protection: the case is easy to carry between workstations while still guarding sensitive standards from shocks. The durable shell minimises wear under regular use and the compact footprint requires little bench space. This combination of robust construction and practical ergonomics helps maintain operational uptime and lowers the total cost of ownership through fewer damaged items and less downtime. Practical compatibility with recognised calibration classes Designed specifically for calibration sets covering 1 mg–2 kg, the case accommodates weights across internationally recognised categories, including E1–M1 classes. These classes indicate the tolerance and intended application range of the weights; E1 denotes the highest precision for laboratory reference standards, while M1 suits routine and industrial checks. The 313-070-600 therefore supports both laboratory-grade storage and workshop-level transport requirements without compromise.
