Wooden case for single weights KERN 317-110-100 — padded, for 1 kg (E1–F1) The Wooden case 317-110-100 is a protective wooden case designed for secure storage and transport of single calibration weights used in precision weighing and test procedures. Padded interior protects calibration weights Compatible with 1 kg single weights Fits KERN models 307/316/317/326/327/329 Durable wooden exterior for workshop use Secure storage that protects measurement accuracy A reliable storage solution helps maintain the integrity of precision weights by preventing knocks, contamination and surface wear. The padded interior absorbs shocks and keeps each weight immobilised, reducing the need for frequent recalibration. Built from wood, the case offers a stable environment that limits abrupt temperature changes and surface contact, which in turn supports consistent weighing results. The tailored design is particularly useful where 1 kg reference masses must be preserved to class E1–F1 tolerances. Designed for compatibility and easy organisation Clear compatibility with established KERN single-weight models removes uncertainty when integrating into existing calibration toolsets. The compact layout provides designated spaces for individual weights, enabling quick identification and rapid handling during regular checks. By organising weights in a stable holder, technicians benefit from reduced handling time and lower risk of damage — a pragmatic efficiency gain for busy workshops and calibration labs that value reproducible results. Practical benefits for workshop workflows Storing calibration weights in a dedicated case reduces downtime associated with searching for or cleaning damaged weights. The robust exterior supports everyday workshop use while the interior padding preserves surfaces and geometry of precision masses. This solution contributes to smoother calibration routines and supports quality assurance processes by keeping reference weights in a ready-to-use state. For environments where traceability and repeatability matter, this case complements a systematic approach to measurement certainty.
