Description
Test weight KERN 347-135 is a single weight of OIML class M1 with a nominal mass of 5 kg. It is configured as a slotted weight of type A and manufactured from finely turned stainless steel conforming to OIML specifications. This individual reference mass is suited to the calibration and routine checking of balances and scales that require M1 accuracy. The slotted type-A geometry permits stacking or combination with other compatible weights when building larger test loads. Finely turned stainless steel delivers a durable, corrosion-resistant surface that maintains mass stability through repeated handling. Supplied as one piece, the weight can serve as a standalone standard or form part of a modular set. Manufactured by Kern, the 347-135 model adheres to the dimensional and tolerance criteria established for OIML M1 slotted weights at 5 kg. Its robust construction supports reliable performance in laboratory, industrial and quality-assurance environments. The type-A slot design facilitates secure placement and removal during verification procedures. Net and gross mass both equal the stated 5 kg nominal value, allowing the unit to function directly as the reference without additional components.

Questions about Test Weight KERN 347-135
What is this article?
Test Weight KERN 347-135 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.
