Description
Wooden weight case KERN 337-050-200 is a protective wooden storage etui designed specifically for single knob or compact test weights of 20 g. It provides a secure, organised housing that safeguards precision calibration masses against dust, mechanical impact and contamination during storage and transport. Compatible with individual weights from the KERN 337, 347, 357 and 367 series, the case ensures that the reference mass remains ready for immediate use in laboratory or industrial calibration routines. Supplied as one piece, this wooden etui offers a practical solution for laboratories, quality-control departments and metrology services that need to protect single 20 g weights between verification cycles. The robust wooden construction from manufacturer Kern delivers durable protection while allowing easy access to the enclosed weight. Ideal for maintaining the integrity of OIML-class test weights in analytical laboratories, production facilities and service workshops, the case helps extend the service life of precision masses by reducing handling damage and environmental exposure. Its compact design fits conveniently into drawers, cabinets or portable calibration kits, supporting orderly storage of individual reference weights used for balance adjustment and routine performance checks.

Questions about Wooden Box for Set of Weights KERN, 337-050-200
What is this article?
Wooden Box for Set of Weights KERN, 337-050-200 is the article on this page. Luminix Health distributes Kern for laboratory use. It sits in Calibration & test weights, inside Balances & scales, in Lab instruments.
A test weight is a mass of a stated class, used to check a balance. The class sets the tolerance. A weight that is dirty, or that has been handled with bare fingers, is no longer that class. The certificate ties the weight to a standard.
A balance compares a mass with a standard. An analytical balance reads to 0.1 mg or finer and needs a draft shield and a stable bench. A precision balance is coarser and faster. A platform scale takes a heavier load. The reading is only as good as the calibration chain back to the kilogram, which is why test weights and a certificate exist. A moisture analyser is a balance with a heater: it records the loss of mass as water leaves. The unit of mass is kept by the BIPM, compared across Europe by EURAMET, and accredited by BELAC. NIST publishes the same measurement foundations.
