KERN 317-030-100 Wooden Case for 5 g Single Weights — Padded, for Classes E1–F1 KERN 317-030-100 is a purpose-made wooden case for safe storage and transport of single calibration weights in knob/compact form, intended for use in workshops and laboratories Padded wooden case for calibration weights Designed for 5 g single weights E1–F1 Compatible with knob/compact weight form Fits KERN models 307, 316, 317, 326, 327, 329 Protect sensitive weights and maintain calibration reliability The padded interior and solid wooden case construction reduce the risk of impact damage and contamination, helping to preserve the nominal mass of delicate 5 g calibration pieces. For high-precision classes such as E1–F1, uncontrolled knocks or dust can affect measurement results; this storage solution minimises those risks and supports consistent weighing outcomes. The internal padding also prevents abrasion between weights, which contributes to longer intervals between recalibrations and lower downtime for quality checks. Storage designed for official calibration classes and traceability The case is dimensioned for knob/compact design single weights and keeps each weight separated and identifiable, aiding traceability in calibration routines. By organising weights by nominal value and class, the case streamlines handling during audits and routine checks. The clear fit for recognised KERN series units ensures a standardised approach to storage in quality-controlled environments and simplifies inventory checks during ISO- or internal-audit procedures. Practical handling for workshop and laboratory workflows Made from durable wood, the case combines a tactile, classic finish with functional protection, making it suitable for bench-top storage or secure transport between test stations. The form factor and lightweight construction (approx. 0.13 kg) allow technicians to move sets quickly without adding unnecessary bulk to instrument cases. The padded compartments cut down on setup time by keeping frequently used single weights immediately accessible and protected, improving operational efficiency. Compatibility with KERN single weights and ease of organisation Specifically matched to a range of KERN single weights, the case accepts models in the 307–329 series and their knob/compact shapes, supporting consistent handling across a set of precision instruments. This compatibility means fewer custom storage solutions and a consistent standard for workshops that rely on KERN weights for verification tasks.
